Evolutionists look at examples of animals adapting to their environments, and they assume that in this way, given enough time and enough tiny changes, primitive frogs have turned into turtles, and fish into philosophers.To read the rest, click on "Designed to adapt?"
Creationists have long agreed that inheritable adaptation happens via natural selection. This helps explain how the kinds represented on the Ark were able to rapidly diversify afterwards into many different varieties, even new species.
On its own, natural selection can only sort (or get rid of) existing information. It cannot generate any new information or variability itself; it can only choose from what is already there. Genes come in pairs, are reshuffled at reproduction, and many exist in at least two forms, so living things have a lot of built-in variability already. Thus the ‘dog kind’ pair on the Ark could have diversified rapidly into coyotes, dingoes, wolves, etc. without any genetic novelty necessarily introduced into their DNA.
In addition to long ages, evolution requires mutations. Random ones. Studies are showing that mutations can actually be targeted, which supports biblical creation science.
