Evolution? What is that thing? Baraminology. The continued quest of Carl Linnaeus.

Is This What Darwin Had in Mind?     04/10/2011      
April 10, 2011 — Evolution is a word loosely used in science these days.  Reporters and scientists talk about “the evolution of” this or that sometimes carelessly, without regard to how the explanation fits old Darwinism or neo-Darwinism.  Has the word evolution become a kind of catch-all hypothesis, for which rigor is no longer necessary?
  1. Survival of the discreetist:  Mark Buchanan on New Scientist coined a term exo-evolution to discuss how aliens evolve: “Aliens who hide, survive” is the idea in a nutshell.  “Has ET evolved to be discreet?” he began.  “An evolutionary tendency for inconspicuous aliens would solve a nagging paradox � and also suggest that we Earthlings should think twice before advertising our own existence.”
        The paradox he mentioned is the Fermi Paradox: the puzzle of why we haven’t found aliens, and they haven’t found us, if the universe is full of them.  “In order to explain the Fermi paradox, [Adrian] Kent [Perimeter Institute, Waterloo, Ontario, Canada] turns to natural selection – and suggests that it may favour quiet aliens.”  From there, the discussion descended into what aliens might want to do.  Evolution as Darwin meant it has no purpose or intention.
  2. Survival of the sprinters:  In another article on New Scientist, Michael Le Page denied that slow and steady evolution (gradualism) wins the evolutionary race.  Darwin might be astonished to hear one of his disciples say, “it’s a sprint – one in which the runners might change direction at any minute.”
        The article told Michael Bell’s observations of stickleback fish that appear to adapt within decades.  They had been “assumed to evolve slowly, over thousands of years,” he said.  “Compared with the gradual process described by Darwin, this is evolution at warp speed.
  3. Instant evolution:  It would be harder to think of evolution any faster than warp speed; but how about instant?  Here’s an easy way to get whiteflies to evolve instantly: just add bacteria.  That was the headline of a press release from the University of Arizona.  Molly Hunter did experiments that showed Rickettsia-infected whiteflies had more offspring.  She assumed this was “instant evolution” on that basis; “In evolution, fitness is the money,” she quipped.  Darwin, Mr. Gradualist himself, would be shocked.
  4. Evolutionary interest:  Can organisms have an evolutionary interest in something?  Darwin assumed that natural selection is random and undirected; Dawkins assumed selfish genes were interested only in their own survival, the organism be damned.  Why, then, did Jiggins and Hurst say this in Science?1  “Being maternally inherited, these microbes have an evolutionary interest only in the production and survival of female hosts; consequently, they have evolved a variety of traits through which they promote the production and survival of daughters.”
        They were talking about a case of horizontal gene transfer in insects: “It has recently become clear, however, that horizontal transfer of traits can play a major role in arthropod evolution.”  Such transfer is contrary to 150 years of speculation about how evolution operates.
  5. Losing sleep over evolution:  Evolution might make you lose sleep.  If you are a cave fish, and lose your eyes, you might be able to get by with less sleep, according to a press release from New York University.  The researchers found behavioral changes in sleep patterns between cave fish and their counterparts on the surface, but did not tie them to any genetic changes, at least yet.  They did not explain whether this made them more fit in some way; if it’s always midnight, does evolution make you burn more midnight oil, and if so, is that good for you or for fish?
It appears from these and many other stories that evolution is a flexible word.  Any change of any kind, no matter how fast or slow it occurs, and whether it produces any fitness gain or not, can be called evolution.  Explanations that become too loose wind up explaining nothing.

  The phrase “the evolution of” now serves the same purpose as “the demon of” has in explanation, as in “the demon of obesity.”  It fits anything and everything the speaker wishes to blame on some unknown quantity operating by an unknown process.
    Darwin might be shocked by these abuses of his theory, but it’s all his fault.  He was the one that introduced storytelling into science.  How is his fiction any better than these?

I prefer to use Darwinism as a complete description of the mindset of those who are so dedicated to the need for ANYTHING BUT GOD that they grasp not only at straws, but the fragments of straws in order to defend a concept that is too difficult to even truly define.   It is too inexact and messy to pin down.   It is a boat riddled by bullet holes attempting to cross an ocean unrepaired.   No one has succeeded in actually taking it out upon the water without sinking.


Carolus Linnaeus is the man who sought to introduce to the world the concept of Baraminology.   He did not have the information that we do now, but in his own way he sought to divide the world of organisms into various family groups.  His attempts were descriptive rather than prescriptive.   Let's let David Coppedge briefly describe his impact on the world of science:


Carolus Linnaeus     1707 - 1778  





It becomes clear that the nested hierarchy is a problem for evolution.  The farther up the scheme, the larger the gaps between types.  At the level of phyla, for instances, think of the huge differences between a starfish (an echinoderm) and a fish (a chordate), or between a beetle (an arthropod) and a snail (a mollusk).  Within each phylum are many common characters, but there are large, systematic gaps between the phyla, classes, orders and families.  House cats, bobcats, lions, tigers and cheetahs share many common characteristics within the cat family, but in every case we know, these are always distinct from members of the dog family.  Dogs and cats belong to the class mammalia, but all mammals are very different from all class aves (birds).  Mammals and birds share characteristics (a backbone) within the phylum chordata (subphylum vertebrata), but all vertebrates are very different from clams in the phylum mollusca.  Higher up, members of the plant kingdom are even more different from members of the animal kingdom.


Taxonomists can be confused about what phylum or class an organism should be placed in, because many animals and plants are composed of mosaics of characteristics from several groups.  Consider the platypus, for example.  It lays eggs like a reptile, has webbed feet like a duck, a venomous spur like a rattlesnake, and fur like a mammal.  Classification can be even more confusing for one-celled organisms.  Some have been recently placed into whole kingdoms separate from plants and animals.  It is often an arbitrary choice where to classify an organism.  The sunflower family, for instance, is kind of a catch-all category for many diverse flowering plants that do not fit well into other families.  Evolutionists have a hard time with these mosaics, often invoking the hand-waving answer “convergent evolution” when asked to explain how “unrelated” organisms share common characteristics, such as the remarkable similarities between placental mammals and their marsupial look-alikes.

Evolutionists believe that variation has no limits and all things are interrelated, but that is a belief, not an observed fact.  Even breeders know they can only take a horse or a rose or a cow or a sugar beet so far before a trait becomes impossible to modify further.  Taking the data as we find it, without an evolutionary presupposition, we see living things organized into groups within groups within groups, with the major groups separated from one another by large gaps.  The Linnaean classification system reflects the observational evidence.  Despite its occasional points of debate or confusion, it has stood the test of time.  Sadly, some evolutionists are trying to push an alternate “PhyloCode” classification scheme, which organizes plants and animals according to their presumed evolutionary relationships.  If successful, this would only cloud the issue.  It would embed evolutionary assumptions into the way students approach the data.

Others before him had shared this passion.  John Ray, the English naturalist who had died two years before Linnaeus' birth, was a like-minded naturalist, who, by the way, was also a Christian and a creationist.  But the universal classification scheme using Latin binomial nomenclature was the innovation Linnaeus brought to the discipline.  He chose Latin because it was not only the universal language of science, but being a dead language, it was stable and unchanging.  It provided a universal scheme that all naturalists in all countries could use to communicate with each other, as well as to publish their discoveries and cross-check their findings against those of others.  At age 40, Carl latinized his own name into Carolus Linnaeus the name by which he is best known.  He moved to Holland in 1735 for three years, then back to Sweden, where he lived out his days as a doctor and professor.  Taxonomy remained his obsessive hobby throughout his life.

Linnaeus at first actually believed it possible to classify every living thing in the world.  At age 25, Carl secured a grant from the University of Upssala to take a thousand mile tour of Lapland to catalog plants.  One can only imagine the delights and dangers, the fatigue and satisfaction this “creation safari” entailed as he waded icy streams, slogged through bogs and avoided nervous landowners.  He kept detailed journals and catalogued thousands of plants.  A similar trip through central Sweden added many more.  Linnaeus traveled over four thousand miles on foot in his quest to catalog all the species in “God’s garden.”  He also leveraged his talent to students that he motivated, who often went on long and arduous journeys to far lands to collect more specimens (Dan Graves said a third of these died on their dangerous treks).  Linnaeus continued updating, expanding and improving his catalogs throughout his life, and as a legacy, he left the Linnaean Society, which continues to this day as an international taxonomic institution.




Linnaeus continued classifying plants and animals into his sixties, till he suffered a series of strokes.  The frontispiece of his magnum opus Species Plantarum, the work that set established taxonomy as a scientific discipline, is a passage from the Psalms that could be viewed as a life verse of all great creation scientists both past and present, who similarly quoted it with feeling: Psalm 104:24 – “O Jehovah [Lord], how ample are Thy works!  How wisely Thou hast fashioned them!  How full the earth is of Thy possessions!”

~~~~~~~~

Interesting that the vast majority of influential scientists of the second millenium AD were believers in God and many of them Christians and not just Deists or Theists.  They are the people who took science away from the axiomatic method and introduced the scientific method of investigation.   Naturalistic Materialists have twisted and broken the actual method by superimposing their metaphysically driven worldview upon said method, but that does not mean we cannot ignore them and do science correctly.

Carl could not have known about all the tools that are now at our disposal to investigate the organism carefully to determine what kind (or baramin) it actually is.    Here is an introductory look at Baranomes and Baraminology and I promise there is more to come.   Creationists are actually building a taxonomy based on actual DNA evidence and reproductive evidence that is superior to Linnaeus' quite admirable efforts.   


Evidence for the design of life: part 2—Baranomes


The major difference between the evolution and creation paradigms is that the evolutionist believes that the natural variation found in populations can explain microbe-to-man evolution via natural selection (Darwinism), while the creationist believes it cannot. This is because the evolutionary, naturalistic framework requires something creationists hold impossible: a continuous addition of novel genetic information unrelated to that already existing. In the creation paradigm neither variation nor selection is denied; what is rejected is that the two add up to explain the origin of species.

In part 1, I discussed genetic redundancy and how redundant genes are not associated with genetic duplications and do not mutate faster than essential genes. These observations are sufficient to completely overturn the current evolutionary paradigm and could form the basis for a novel creationist framework help us understand genomes, variation and speciation. In this second part, I argue and provide biological evidence that life on Earth thrived due to frontloaded baranomes—pluripotent, undifferentiated genomes with an intrinsic ability for rapid adaptation and speciation.

Where redundancy leads

The canonical view is that most variation in organisms is the result of different versions of genes (alleles) and genetic losses. The variation Mendel studied in peas and that led him to discover several basic inheritance laws, was the result of different alleles. At least, so it is taught. One of the seven traits Mendel described in peas was what he called the I locus—it referred to the colour of the seeds. In Mendel’s jargon, ‘I’stood for dominance (yellow), whereas ‘i’meant recessive (green). Plants carrying I had yellow seeds, plants lacking I had green seeds. Mendel shed scientific light on inheritance.

Baranomes

Now, 140 years after Mendel’s findings, we know how the yellow-green system works at the molecular level. The colour is determined by the stay-green gene (abbreviated: STG) that codes for a protein involved in the re-absorption of green pigments during senescence.1 The recessive trait i is the mutated form of the STG gene; an inactive variant that cannot re-absorb pigments, so the seeds keep their green colour.

Is the STG gene essential for survival? Most likely it is not. Molecular biology shows Mendel studied the effects of non-essential and redundant genes. Dominance means at least one redundant or non-essential gene is functional; recessive means both copies of redundant and non-essential genes are defunct. In Bacillus subtilis only 270 of the 4,100 genes are essential,2 and in Escherichia coli this is a meagre 303 out of a total of almost 4,300 genes.3 Genetic redundancy is present everywhere,4 and this lead me to believe that biology is quite different from what Darwinians think it is. Namely, organisms are full of genetic tools that are handy but not essential for survival, and selection cannot be involved in shaping these genes. Apparently, genomes are loaded with genetic elements that reside in the genome without selective constraints. This makes sense in the creation paradigm, because the genomes we observe today are remnants of the original genomes in the created kinds. And, apparently, they were created as pluripotent,5 undifferentiated genomes with an intrinsic ability for rapid adaptation and speciation. I have called the undifferentiated, uncommitted, multipurpose genome of a created kind a baranome.6 Baranomes explain genetic redundancy: there is no association with gene duplication, and redundant genes do not mutate faster than essential genes.4

Saccharomyces bn

The lack of understanding of baranomes recently led to a severe misinterpretation of the origin of genes in the secular literature. Eager to find evidence for the evolution of novel biological information, a novel de novo protein-coding gene in Saccharomyces cerevisiae was reported on the basis of genome comparison among several species of Saccharomyces. The BSC4 gene had an open reading frame (ORF) encoding a 132-amino-acid-long polypeptide. It was reported that there is no homologous ORF in all the sequenced genomes of other fungal species, including closely related species such as S. paradoxus and S. mikatae. The sequences presented in the figure above demonstrate, however, that the BSC4 gene can be found interrupted and inactivated in S. paradoxus, S. mikatae and S. bayanus. These data confirm the baranome hypothesis, which holds that all Saccharomyces descended from one original undifferentiated genome (Saccharomyces bn) containing all information currently found in the isolated species. This alleged novel gene is in fact ancient frontloaded information that became redundant and inactive in most S. spp but was subject to sufficient constraints to be retained in S. cerevisiae. BSC4 codes for a protein involved in DNA repair; an elaborate and integrated mechanism involving dozens of redundant systems. Therefore, it is predicted that BSC4 knockouts of S. cerevisiae will not show major problems. The top part of the figure shows the alignment of 320 base pairs of the orthologous sequences of BSC4 from Saccharomyces bayanus (S.bay), S. mikatae (S.mik), S. paradoxus (S.par) and S. cerevisiae (S.cer). The conserved nucleotides are shown in bold. (Adapted from Cai and Zhao et al.34). The bottom of the figure shows how only S. cerevisiae retained an active BSC4 gene.

The multiple genomes of Arabidopsis

In 2007, Science reported on the genome of Arabidopsis thaliana, a flowering plant of the mustard family with a small genome that is suitable for extensive genetic studies.7 This report was of particular interest because it showed the genomes of 19 individual plants collected from 19 different stands, ranging from sub-arctic regions to the tropics. According to a commentary summarizing the results of this painstaking analysis
‘ … about four percent of the reference genome either looks very different in the wild varieties, or cannot be found at all. Almost every tenth gene was so defective that it could not fulfill its normal function anymore!
‘Results such as these raise fundamental questions. For one, they qualify the value of the model genomes sequenced so far. “There isn’t such a thing as the genome of a species,” says Weigel. He adds “The insight that the DNA sequence of a single individual is by far not sufficient to understand the genetic potential of a species also fuels current efforts in human genetics.”
‘Still, it is surprising that Arabidopsis has such a plastic genome. In contrast to the genome of humans or many crop plants such as corn, that of Arabidopsis is very much streamlined, and its size is less than a twentieth of that of humans or corn—even though it has about the same number of genes. In contrast to these other genomes, there are few repeats or seemingly irrelevant filler sequences. “That even in a minimal genome every tenth gene is dispensable has been a great surprise”, admits Weigel [emphases added].’8
Among the 19 stands of Arabidopsis we find dramatic genetic differences. We observe genetic losses as well as genetic novelties. Although the dispensability of genes is easy to understand with respect to genetic redundancy, the observed novelties are much harder to conceive unless we accept that all observed novelties are not novelties at all but genetic tools that have resided in the genome since the day Arabidopsis was created. The genetic ‘novelties’ may simply reflect environmental constraints that have helped preserve these genetic tools.

There is indeed ‘no such thing as the genome of a species’, because what we observe today are rearranged and adapted genomes that were all derived from an original genome that contained all genetic tools we find scattered throughout the population. The ‘great surprise’ is only a great surprise with respect to the Darwinian paradigm. With a pluripotent Arabidopsis genome in mind, the data are not surprising at all. It is in accord with what we might expect from the perspective of a rapid (re)population of the earth.

Modern Arabidopsis genomes look as if they were derived from much larger genomes containing an excess of genetic elements—both coding and non-coding (repetitive) sequences—that can easily be lost, shuffled or duplicated. The ‘dispensable genes’ outlined above can be understood as genetic redundancies originally present in the baranome that over time slowly but steadily fell apart in the 19 individuals, because the environment did not select for them. The study strongly suggests that isolated stands of plants originated as a result of loss of genetic redundancies, duplication and rearrangement of genetic elements. The dispensability of 10% of the genes of Arabidopsis could have been predicted because most of the genes still present in individual genomes are redundant.9 In my opinion, these observations strongly favour the baranome hypothesis.

The law of natural preservation

Genetic redundancy, dispensable genes and disintegrating genomes are scientific novelties revealed to us by modern biology. How can we understand all this? Darwinians hypothesize that life evolved from simple unicellular microbes to multicellular ones via a gradual build-up of biological information, the driving force supposedly being natural selection. According to biology, there is no gradual accumulation of information; biology originated from a ‘big bang’. Sponges, worms, plants and man all have approximately the same genetic content, so the number of genes does not seem to be related to the complexity of organisms.10 In addition, the complex organisms we observe today were not derived from a single or a few simple organisms, but must have derived from a global community of organisms.11 The observations of modern biology pose so many untenable hurdles for naturalistic philosophy that it would be better to simply leave Darwinism for what it is: a set of falsified 19th century hypotheses that do not and cannot explain the origin of species.

Baranomes were multifunctional genomes which can be compared to a Swiss army knife.

The way to understand variation and speciation is through disintegration and rearrangement of primordial baranomes created with an excess of genetic elements. Baranomes initially contained all mechanisms required to quickly respond and adapt to changing environments. They provided organisms with the tools needed to invade many distinct niches, and were ideal for the swift colonization of all corners of the world. Baranomes were multifunctional genomes which can be compared to a Swiss army knife. A Swiss knife contains many functions which are not immediately necessary in a particular environment; but some of them are extremely handy in the mountains, others in the woods, still others are made for opening bottles and cans, or tools for making a fire. Depending on where you are, you may require different sets of functions. Similarly, depending on where the organism lives, it demands different functions (i.e. protein-coding genes and their protein products) from its genome. The environment then determines what part of the non-essential genome is under constraint and it is only this part that will be conserved. In other words, the law of natural preservation—conventionally coined ‘natural selection’—determines the differentiation of the pluripotent genome.12

Phylogeny of modern Flaveria species demonstrates independent losses of the C3 and C4 photosystems from the baranome of Yellowtops species (Flaveria bn). Some have either the C3 or the C4 photosystems, others have both C3 and C4 (or parts there of). Isolated species are in the process of losing redundant parts of the Flaveria baranome.

(Adapted from Kutchera and Niklas14). 

C3 and C4 plants

From the creation paradigm, we might expect to find more than one carbon-fixation system. For example a system that functions optimally in warm, tropical regions, also systems that operate at sub-arctic temperatures. We find that plants do indeed have two photosystems for fixing carbon fixation; they are known as C3 and C4. The optimum temperature for carbon fixation in C3 plants is between 15–20ºC, whereas the C4 plants have an optimum around 30–40ºC.13 Today many plants are either C3 plants or C4 plants, but we also find plants that have both C3 and C4. There is clear indication for redundancy of the two photo-systems, because many plants have only one of both systems operable; either C3 or C4, plus remnants of the other system.

For instance, in modern Yellow tops (Flaveria spp) we not only see functional C3, C4 or the combination of C3 plus C4 photo-systems, but we also observe C4 remnant in C3 plants.14 The presence of remnants of one of the systems qualifies as evidence for a baranome containing both photo-systems, and indicates that the C4 system is not stringently preserved when the C3 system is also present (figure 1). The two ‘frontloaded’ photosystems ensure a rapid colonization of both high and low altitudes, and hot and cold environments. In the tropics, the C4 system, which functions optimally at high temperatures, should be active, whereas the C3 system is redundant. Here, the ‘hot’ system would be under permanent environmental constraint and be conserved. Due to accumulation of debilitating mutations in the genetic elements comprising cold systems, these would rapidly disintegrate. A genetic program designed for tropical regions does not make sense in arctic regions, and vice versa. It is the organism’s environment or habitat that determines whether genetic elements are useful or not. Conforming to the baranome hypothesis, the habitat determines genetic redundancy. There is no biological reason to assume why unused, habitat-induced redundancies should be preserved. The law of natural preservation tells us that unused genes will rapidly degrade.

What baranomes contain

Baranomes are information carriers. They were frontloaded with three classes of DNA elements: essential, non-essential and redundant. When essential elements mutate to change the amino acid sequences, the information carrier as a whole is immediately subject to a severe reproductive disadvantage. In the worst case the mutation is incompatible with life and mutated essential DNA elements will not be present in the gene pool of the next generation. Essential DNA elements can be defined as biological information that is unable to evolve. Non-essential genes are genes that are allowed to mutate and may thus contribute to allelic variations. As they produce non-lethal phenotypes, they contribute to the variation observed in populations. Classic Mendelian genetics is largely due to variation in non-essential genes. Variation in non-essential genes is what geneticists call alleles. Recessive Mendelian traits can usually be attributed to dysfunctional non-essential genetic elements; in particular elements that determine expression of morphogenesis programs, including those that determine length and shape—‘the morphometry’—of the organism. To induce the recessive trait the disrupted (or inactivated) alleles must be inherited from both parents, because an active wild-type gene usually compensates for an inactivated gene. In Mendel’s jargon, this compensation is known as dominance.
The third class of frontloaded genetic elements are correct genes that underlie genetic redundancy. They make up a special class of non-essential genes and have only recently been discovered. That is because their existence cannot be deduced from genetic experiments: they do not contribute to a detectable phenotype. Their peculiarity is that redundant genes may be completely lost from the genome without any effect on reproductive success. That redundant genetic elements make up a major part of the genome of all organisms became evident when biologists interested in gene function developed gene-knockout strategies; with the remarkable observation that many knockouts do not have a phenotype.4 Genetic redundancy is an intrinsic property of pluripotent baranomes. It should be noted, however, that the environment also plays a crucial role in determining whether a genetic algorithm is redundant, non-essential or essential. The pathway for vitamin C synthesis, for instance, is a diet-induced genetic redundancy which is inactive in humans, four primates, guinea pigs and fruit-eating bats as a result of two debilitating mutations.15

The law of natural preservation often dictates the course for the development of baranomes. In addition, baranomes initially contained variation-inducing genetic elements (VIGEs) that helped to induce rapid duplications and rearrangements of genetic information. Modern genomes of all organisms are virtually littered with VIGEs (which are usually referred to as remnants of retroviruses; LINEs, SINEs, Alus, transposons, insertion sequences, etc.) and due to their ability to duplicate and more genetic material they facilitate and induce variation in genomes.16

Speciation from baranomes

Variation in reproducing populations is mostly due to position effects of VIGEs. That is because the presence of VIGEs in or near genes determines the activity of those genes and hence their expression.17 Variation is a result of a change in gene expression. In addition, VIGEs that function as chromosome swappers may also help us understand reproductive barriers. A reproductive barrier between organisms is in fact another term for ‘speciation’, the formation of novel species. ‘Species’ is meant here in the sense of Ernst Mayr’s species concept, which includes intrinsic reproductive isolation.18 Indeed, the gene swapping mechanism present in primordial pluripotent genomes also allowed for intrinsic reproductive isolation. If we want to understand how chromosome-swapping VIGEs are involved in speciation, we first have to look into some details of sexual reproduction.

In all cells of sexually reproducing organisms the chromosomes are present as homologous pairs. One is inherited from the father and the other from the mother. The arrangement of homologous chromosomes allows them to easily pair up. Each parental chromosomes recognizes the other and they easily align. The alignment is necessary for the formation of gametes during meiosis, where the two sets of parent chromosomes are reduced to one set. Differences in chromosome pattern impede the pairing of chromosomes at meiosis, resulting in hybrid sterility. Chromosomal rearrangements may be one of the most common forms of reproductive isolation, allowing rapid adaptive radiation of multipurpose genomes without the need for geographic isolation or natural selection. The activity of chromosome-swapping VIGEs may thus have produced reproductive barriers and hence facilitating speciation.

If it is true that chromosomal order determines whether organisms are able to reproduce, speciation can theoretically be reversed by chromosomal adjustments. In other words, we must be able to produce viable offspring from two reproductively isolated species just by rearranging their chromosomes. This may sound like an untestable hypothesis, but experimental evidence demonstrates that it is indeed possible to ‘unspeciate’ distinct, reproductively isolated, species by chromosomal adjustments. Using Mayr’s species definition, yeasts of the genus Saccharomyces comprise six well-defined species, including the well known baker’s yeast.19 The Saccharomyces species will readily mate with one another, indicating that they stem from one single baranome (figure 2), but pairings between distinct species produce sterile hybrids. Three of the six species are characterized by a specific genome rearrangement, known as reciprocal chromosomal translocations.

Reciprocal chromosome translocation occurs when the arms of two distinct chromosomes are exchanged. Analysis of the six species revealed that translocations between the chromosomes do not correlate with the group’s sequence-based phylogeny, a finding that has been interpreted as ‘translocations do not drive the process of speciation’. However, a study carried out by the Institute of Food Research in Norwich, United Kingdom, showed that the chromosomal rearrangements in Saccharomyces do indeed induce reproductive isolation between these organisms.19 The reported experiments were designed to engineer the genome of Saccharomyces cerevisiae (baker’s yeast) so as to make it collinear with that of Saccharomyces mikatae, which normally differs from baker’s yeast by one or two translocations. The results showed that the constructed strains with imposed genomic collinearity allow the generation of hybrids that produced a large proportion of spores that were viable. Viable spores were also obtained in crosses between wild-type baker’s yeast and the naturally collinear species Saccharomyces paradoxus, but not in crosses between species with non-collinear chromosomes.

Left panel: Adaptive radiation from one single pluripotent baranome. The figure shows a hypothetical model for the radiation of the Saccharomyces bn into the six Saccharomyces species we observe today. Initially, the uncommitted pluripotent baranome radiated in all possible directions. Due to intrinsic mechanisms, variation is constantly generated but slowed down over time because of the redundant character of the variation-inducing genetic elements (and were easily lost). Speciation may occur when a reproductive barrier is thrown up, for instance as the result of chromosomal rearrangements. Genetic elements that facilitate variation are specified in the genome and there is no need for the millions of years that are required for Darwinian evolution. This is clear from the long-running (20 years) evolutionary experiments which show that the major adaptive changes occurred during the first 2 years.35 Right panel: Hypothetical time courses for the total amount of information in a baranome (black line) and the number of species derived from that baranome (pale line). Over time there is a tendency to lose biological information with an increase of the number of species.

Over time there is a tendency to lose biological information with an increase of the number of species. 

This is empirical proof that a reproductive barrier between species can be reversed just by reconfiguration of their chromosomes. In addition to reciprocal chromosomal translocations, many small-scale genomic rearrangements, involving the amplification and transposition of VIGEs may cause reproductive isolation. VIGEs are thus basic to understanding variation and speciation of baranomes. Modern biology demonstrates that although the six species of Saccharomyces yeasts are all derived from one single baranome, their individual karyotypes20 determine whether they can interbreed and leave offspring.

That the karyotype is an important determinant of reproductive isolation is also observed in deer. Eight species of Asian deer of the genus Muntiacus inhabit an area speading from the high mountains in the Himalay to the low land forests of Laos and Cambodia. Their karyotypes differ dramatically; chromosome number varies from a low of only three pairs to a high of 23.21 The muntjack species demonstrate that individuals that differ substantially by chromosomal reorganizations of otherwise identical genetic material will invariably be sterile. The sterility of muntjack hybrids is exclusively due to the inability of the chromosomes to pair. The chromosomes of distinct species simply cannot form pairs, and formation of viable reproductive cells is impossible. The karyotype accounts for reproductive isolation, and the baranome hypothesis leaves room for speciation events through adaptive radiation.

Identification of baranomes

How do we identify whether organisms descended from one primordial multipurpose genome? Darwinians claim a continuum between genomes of distinct species and view all modern species as transition stages, so this question is not of particular interest. For micro-organisms this may well be true. Between bacteria, the exchange of biological information is common and for this purpose they possess elaborate mechanisms to facilitate the uptake of foreign DNA from the environment. Still, over 5,000 distinct bacteria have been scientifically described, indicating distinctive borders between bacterial ‘species’.22

Likewise, the biological facts in higher organisms these are distinctive borders between genomes; borders determined by reproductive barriers. For instance, humans and chimps both have comparable genomic content, but very distinctive karyotypes, so the species cannot reproduce with each other. Therefore, the question raised above is not easy to answer. Because genomes tend to continuously lose unused genetic information over time, genomic content may not be suitable to identify common descent from the same primordial baranome.

A first indication that two distinct species have descended from the same baranome is this ability to mate. The offspring does not have to be fertile; neither does it have to be viable at birth.
A first indication that two distinct species have descended from the same baranome is this ability to mate. The offspring does not have to be fertile; neither does it have to be viable at birth. Zygote formation is a significant indication that the organisms were derived from the same baranome.

The best tool for baranome identification currently available, however, may be indicator genes. Indicator genes are essential genes with a highly specific marker. In the human baranome (Homo bn) we indeed observe indicator genes, such as FOXP223 and HAR1F.24 Both genes are also present in primates, but in humans they have highly specific characteristics not found in primates, indicating that human genomes stem from a distinct baranome. Specific characteristics typify humans. A comparative analysis of indicator genes in primates is sufficient to discriminate between man and chimpanzee (Pan bn) baranomes, or whether ancient bones belong to the human baranome. Recent research shows that indicator genes may indeed be a promising tool for baranome detection. Analyses of ancient Neandertal DNA, revealed typical human FOXP2 characteristics.25 This observation is compelling evidence that both modern humans and Neandertals originate from one and the same baranome. Further research is required to develope a full range of baranome indicator genes for other organisms.

Darwin revisited

From the baranome hypothesis we can begin to understand how Africa’s Rift Valley lakes became populated with hundreds of species of Cichlids within a mere few thousand years. We can also understand the origin of dozens of (sub) species of woodpeckers, crows, finches, ducks and deer. And we begin to see how wings could develop many times over in stick insects.26 We also understand why two distinct sex systems operate in Japanese wrinkled frogs (Rana rugosa),27 and why Dictyostelium has genetic programs for both sexual and asexual reproduction.28 And we begin to see why ancient trilobites radiated so rapidly.29 The required genetic programs (Dictyostelium’s sexual reproduction program make up over 2,000 genes!) did not have to evolve step-by-step under the guidance of natural selection. Rather, these programs were a ‘dormant’ frontloaded part of the baranome and only required a ‘wake-up call’. If Darwin had the knowledge of 21st century biology, I believe his primary conclusion would be similar to what I propose: limited common descent through adaptive radiation from pluripotent and undifferentiated baranomes. The limits to common descent are determined by the elements that have been frontloaded into that baranome. Natural varieties of sexually reproducing organisms can be established by means of differential reproductive success, but reversal to wild types follows as soon as selective constraints are relieved and hybridization between previously isolated populations occurs. Hybridization is, in fact, nothing but reversal to a more original multipurpose genome; the wild type is the more stable (‘robust’) form of the baranome because it contains more redundancies. Reversal to the wild-type was a known principle in Darwin’s day, but Darwin dismissed the obvious and invented his own naturalistic biology:
‘To admit this view [of unstable created species] is, as it seems to me, to reject a real for an unreal, or at least for an unknown, cause. It makes the works of God a mere mockery and deception; I would almost as soon believe with the old and ignorant cosmogonists, that fossil shells had never lived, but had been created in stone so as to mock the shells now living on the sea-shore.’30
Darwin rejected the baranome for theological, or at best for philosophical, reasons. Why would a flexible, highly adaptable, pluripotent genome present in primordial creatures make God’s work ‘mere mockery and deception’? A pluripotent genome with an intrinsic propensity to rapidly respond to changing situations elegantly explains ‘the co-adaptations of organic beings to each other and to their physical conditions.’
Organisms that cannot adapt or, in other words, organisms that lose their ‘evolvability’ are bound to become extinct. The baranome hypothesis with frontloaded VIGEs is sufficient to explain what Darwin observed and there is no need to invoke a gradual and selection-mediated evolution from microbe-to-man, which is non-existing and not in accord with scientific observations anyway. In every generation, VIGE activity generates novel genetic contexts for pre-existing information and hence gives rise to novel variation. VIGEs were an intrinsic property of baranomes, and they are the source of variation and adaptive radiation. It must be emphasized that, because all elements that induce variation are already in the genome, there is no need for the millions of years required for Darwinian evolution.

Conclusion and perspective

The findings of modern biology show that life is quite different from that predicted by the evolutionary paradigm. Although the evolutionary paradigm assumes an increase of genetic information over time, the scientific data show that an excess of biological information is present even in the simplest life forms, and that we instead observe genetic losses. A straightforward conclusion therefore should be that life on Earth thrived due to frontloaded baranomes—pluripotent, undifferentiated genomes with an intrinsic ability for rapid adaptation and speciation. Baranomes are genomes that contained an excess of genes and variation-inducing genetic elements, and the law of natural preservation shaped individual populations of genomes according to what part of the baranome was used in a particular environment.

With so many genomes sequenced and an ever increasing knowledge of molecular biology, we will find more and more evidence to support the baranome hypothesis. We will increasingly recognize traces and hints of frontloaded information still present in the genomes of modern species. We may expect that the genomes of the descendants of the same multipurpose genome independently lost redundant genetic elements. We may expect to find impoverished genomes and also reproductively isolated populations at different latitudes to be highly distinct with respect to their genomic content. We may even be able to piece together the genomic content of the original multipurpose genome of these species simply by adding up all unique genetic elements present in the entire population.

Finally, it will be possible to detect indicator genes, such as the FOXP2, which may become genetic tools for establishing the borders between distinct baranomes. Frontloaded baranomes are an important tool to help us understand biology. I believe there is grandeur in this view of life, where the Great Omnipotent Designer chose to breathe life into a limited number of undifferentiated, uncommitted, pluripotent baranomes; and from these baranomes all of the earth was covered with an almost endless variety of the most beautiful and wonderful creatures.31 Or, as the Bible says, ‘Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so.’

Karyotype rearrangements

In 1970, Neil Todd developed the karyotypic fission hypothesis (KFH)32 to correlate the physical appearance of chromosomes with the evolutionary history of mammals. Todd postulated wholesale fission of all medio-centric chromosomes. Todd’s fast-track, single event, genome rearrangement still is the most parsimonious theory to account for mammalian karyotypes and potentially explains rapid speciation events. Todd’s was rejected mainly because it postulated something opposing the dominant Darwinian paradigm.

In 1999, Robin Kolnicki revived Todd’s KFH. Although her kinetochore reproduction hypothesis33 was largely theoretical, each step had a known cellular or molecular mechanism. During DNA replication, just before meiotic synapsis and sister chromatid segregation, the formation of an extra kinetochore on all chromosomes is facilitated. The kinetochore is the organizing centre that holds the sister chromatids together during meioses and is composed mainly of repetitive DNA sequences. The freshly added kinetochores do not disrupt the distribution of chromosomes to daughter cells during meiosis because tension-sensitive checkpoints operate to prevent errors in chromosome segregation. The result is a new cell with twice the number of telocentric chromosomes.10

The duplication of the kinetochores on many chromosomes at the same time is highly unlikely in a naturalistic model, but the telocentric chromosomes of rhinoceros, rock wallaby and many other species are physical evidence that their genomes were formed instantly.

I postulate that the genomes, as we observe them today, are the result of thousands of years of rearrangements (fission, fusion and duplications) brought about by specific variation-inducing genetic elements (VIGEs). Initially, well controlled rearrangements may have been facilitated by these elements, but over time the control over regulated genome rearrangement deteriorated. VIGEs may be the genetic basis to help us understand wholesale genomic rearrangements from pluripotent baranomes.

In order to rapidly occupy novel niches, a mechanism or ability to create reproductive barriers may have been intrinsic to baranomes. The ability to adapt, including speciation-events, is merely due to neutral rearrangements of chromosomes, and the VIGEs involved may easily become inactive because of the permanent accumulation of debilitating mutations. The remnants of VIGEs can still be found in contemporary genomes; they are known as (retro)(trans)posons, LINEs, SINEs, Alu insertion sequences, etc. Some VIGEs may have started a life of their own and now jump around more or less uncontrolled.

"Interesting that the vast majority of influential scientists of the second millenium AD were believers in God and many of them Christians and not just Deists or Theists. They are the people who took science away from the axiomatic method and introduced the scientific method of investigation. Naturalistic Materialists have twisted and broken the actual method by superimposing their metaphysically driven worldview upon said method, but that does not mean we cannot ignore them and do science correctly"

Exactly how did modern scientists change the scientific method of investigation?

And what possesses these modern baraminologists that they want to discard the work of Linnaeus, which he performed in the service of God? Just because it clashes with a particular interpretation of a religious work?

So many words, so little sense.

1. Yes, evolution can occur in different forms and at different speeds.

2. "Explanations that become too loose wind up explaining nothing."

Any theory explaining the variety of species that we can see is going to have to cover an amazing amount of different contingencies. The subject matter is simply too broad for a simple explanation that happens to work across the board. The principle of evolution through natural selection is broad enough to apply to a huge variety of circumstances, but the ways in which it is witnessed will still boggle the mind. That's not because the theory of evolution is inadequate, but because nature itself covers such a huge spectrum.

But why deride the theory of evolution when there is not a single alternative scientific theory that can explain the variety of species? Creationists aren't even trying to come up with one.

3. The Fermi paradox... even though the odds that life will have evolved somewhere else in one of the millions of galaxies, the odds of them having evolved close enough to us in time and space (e.g. at this point in time they could be at a very primitive stage, or vastly more advanced) for us to be able to contact them is quite small.

For evolution to apply and favor "quiet aliens", there would have to be evolutionary pressure, first of all. And for that there would need to be some kind of contact and interaction. Otherwise natural selection simply doesn't apply.

5. Re. "Instant evolution": evolution is both instant and gradual, but of course this refers to different things. Each individual instance, each degree, is instant within an organism. It happens the moment that the mutation occurs.

What is not so instant is how long it may take for this mutation to spread through a population, if it does at all. And what is even less instant is numerous such mutations to add up to a significantly different organism. This process may indeed take millions or billions of years.

radar said...

I have already posted many articles that spell out how speciation occurs and why the evidence points to design features within the organism that drive speciation. Natural selection is a description of a designed creation. Rapid speciation has been demonstrated and it involves pre-existing information and processes within the organism. But no macroevolution has been observed. Furthermore we have identified the reason it is not observed. The same designed system that allows for variation within the kind prevents alteration OF the kind. So there will never be a frog turning into a newt or a lizard turning into a bird.

radar said...

I should have made that point stronger. Science knows the basics of how cells reproduce and how speciation occurs and they know that it is a process that is very intricated and sophisticated with portions of the DNA strand doing multiple functions. Meta information and pre-set switches and other parts of the process demonstrate a brilliantly designed means by which kind is preserved yet can vary quickly according to ecological pressures. Life is designed. There is no doubt of it unless you willingly close your eyes to what we have found in the cell. You have to be a fool not to accept this. We have already defined what a fool is - has nothing to do with your intellectual capacity and everything to do with your acceptance or rejection of the Creator. God made everything. Scientists should quit wasting time trying to prove otherwise and work on healing Crohn's Disease and cancers of various kinds and etc.

Matter and energy-> no one knows. Yet.

Life -> an emergent property of a sufficiently-complex, self-sustaining system of chemical reactions.

Information -> appears spontaneously given the right conditions.

Jon Woolf said...

As for this post: as usual, it's riddled with misunderstandings and misstatements about science in general and evolutionary theory in particular. Case in point:

Darwin assumed that natural selection is random and undirected;

Just the opposite: Darwin assumed that variation was random and undirected. On the other hand, he believed, and demonstrated clearly, that natural selection was emphatically non-random. Today we know he was right in both particulars, with the caveat that genetic variation isn't entirely random, because some variations are just plain impossible. Natural selection is so non-random that it can be accurately predicted, given enough information.

Jon Woolf said...

Oh, one more thing: "Scientists should quit wasting time trying to prove otherwise and work on healing Crohn's Disease and cancers of various kinds and etc."

For those who don't know it, Crohn's Disease is a chronic bowel disease that can cause all sorts of unpleasant gastrointestinal symptoms. Medical science has not, as yet, produced any reliable drug-based treatments for it ...

... but intelligent layfolk, applying the concepts of evolutionary science and "Darwinian medicine," have found some moderately successful therapies. Many Crohn's disease sufferers have reduced or even eliminated their symptoms by following any of several 'natural' or 'raw food' diets. These diets eschew the highly processed, chemical-laden foods that most of us in Western society eat, in favor of foods with little or no processing -- foods more like the diet that humans evolved to eat, and did eat for most of our recorded history.

radar said...

There is nothing "Darwinist" about eating real food! Humans didn't evolve to eat vegetables, you are spinning like a top! Furthermore good eating habits don't cure Crohns, we need science to figure out what does because right now we have no real cure for it.

radar said...

Woolf, you read Darwin's mind? He didn't think up natural selection, a creationist did. He borrowed the term and tried to apply it to a random causation. But it is in fact a designed system. That is why we can predict it to some extent. Animal (and vegetable) husbandry has been practiced for many centuries, long before Darwin or Mendel were born. We even see references to it in the Bible.

Jon Woolf said...

"Woolf, you read Darwin's mind?"

I read Darwin's books, which is almost as good. You should try it some time.

Yes, believe it or not, Crohn's disease (and several other chronic bowel ailments) can sometimes be treated with specific diets. One thing those diets have in common is reducing or eliminating the processed foods that so many of us eat, like potato chips, pasta, white bread, etc. This is entirely in line with evolutionary theory, which suggests that humans evolved to eat a specific diet, that modern Western processed foods have little in common with what we evolved to eat, and that therefore certain diet-triggered problems, such as some cases of Crohn's disease, can be treated by reverting to a more natural diet.

And y'know something? In a lot of cases, it works. Unlike creationism.

radar said...

"Genetic redundancy, dispensable genes and disintegrating genomes are scientific novelties revealed to us by modern biology. How can we understand all this? Darwinians hypothesize that life evolved from simple unicellular microbes to multicellular ones via a gradual build-up of biological information, the driving force supposedly being natural selection. According to biology, there is no gradual accumulation of information; biology originated from a ‘big bang’. Sponges, worms, plants and man all have approximately the same genetic content, so the number of genes does not seem to be related to the complexity of organisms.10 In addition, the complex organisms we observe today were not derived from a single or a few simple organisms, but must have derived from a global community of organisms. The observations of modern biology pose so many untenable hurdles for naturalistic philosophy that it would be better to simply leave Darwinism for what it is: a set of falsified 19th century hypotheses that do not and cannot explain the origin of species."

You spout unsupported opinion, I go on evidence.

Microevolution is actually just speciation. It involves the shuffling and redistribution of preexisting genetic material and is in no way a Darwinist concept nor does it do anything but disprove Darwinism.

"Baraminology is the continuation of the work of Linnaeus, not a repudiation."

So much misinformation and faulty logic packed into such a short paragraph:

1. Microevolution is not speciation and speciation is not microevolution. Speciation is the evolution of new species and is therefore part of macroevolution, which is evolution at the species level and above.

2. Why would the reshuffling of existing genetic material not be a "Darwinist concept"? It's part of the theory of evolution.

3. What makes you think that the reshuffling of existing genetic material (which sounds a lot like a mutation to me) would not be part of evolution?

4. In what possible way do you think microevolution disproves Darwinism? It's part of the theory of evolution...

Since Jon Woolf showed up on your blog (courtesy of you plagiarizing one of his pictures), he has falsified just about every creationist claim you've ever made. Your shifty evasion is hilarious - he didn't answer question X, so all the other questions don't matter.

"Let's see him or anyone else explain the advent of matter and energy and life and information without a First Cause and then we'll talk."

You're begging the question (logical fallacy) by positing an "advent". Obviously, if there was an advent of matter and energy, then there must have been a first cause, whatever it was. But we don't know that there was such an advent, so the question is moot.

As for life and information, we know there was a time when they didn't exist, and we know they exist now, so we can conclude that there was an advent of these. However, naturalistic explanations for the origin of life are not out of the bounds of possibility, and the creation of information via natural selection is certainly possible, and can be demonstrated in simulations - but that's something you're afraid to contemplate.

Radar,

1. Could you please explain how reproduction with variation plus natural selection amount to a designed system?

2. Could you explain how one could deduce that it is a designed system and could not be simply an aspect of the natural world? Seems to me that once reproduction with variation is in play, natural selection is an inevitable consequence.

And reproduction with variation is something that can occur naturally.

It appears that the Darwinist commenters aim their comments at the least informed readers. There was no second Isaiah. The measurements of cubits they were arguing about have been explained in great detail about a year ago on this blog, so why bring it back up? Also, the Hebrew word some call "circle" is a word meaning round or roundness and can imply a circle or a ball or a cylindrical object even.

I am going to concentrate on posting good content for the audience from a wide array of sources so that soon people will see that Darwinism is wrong and that Creationists have a much more logical view of the world and their beliefs fit the evidence, unlike the Darwinists.

Since genetic material is required for speciation, evolution cannot explain where genetic material comes from, and I did post proof that Darwin just took the concepts of natural selection from other people and published them. Problem is that evolution cannot explain genetic information. Shuffling cards doesn't tell us where cards came from?"

Um, Radar, is this you talking about yourself in 1st and 3rd person in the same post?

If you didn't find Woolf's pictures on his blog, then where did you find them?

Folks, I don't even have a blog. The two pictures in question were taken from my website -- specifically, from my four-page illustrated essay on how the Grand Canyon refutes young-earth creationism.

And yes, both the pictures in question are in fact mine. One comes from my trip to Grand Canyon in 1999, the other from my trip to Mount St Helens in 2002.

Radar can't have found those pictures on my blog, because I don't have a blog. The two photos we're talking about were clearly copied directly from a page on my website, along with their captions. He can't have gotten them from anywhere else.
