Horseshoe Crab Defies Evolution, Helps Medical Science

Way back when, Papa Darwin referred to critters that are found in the fossil record and are also doing right well today as living fossils. Such things troubled Darwin, and his disciples are making excuses even today. One of those living fossils is an arthropod called the horseshoe crab. It looks like an armored land and sea vehicle for a tiny invader. Yes, I've been watching science fiction again.

In addition to defying evolution and affirming recent creation, horseshoe crabs are also providing some medical benefits from their blue blood. It can be used to detect toxins on things that get put into a human body. Don't worry, they're not bled dry and tossed in the trash can. They're actually released so they can go on about doing crab stuff. Scientists are working on using recombinant DNA technology to mimic the blood. Of course, they praise Darwin, (blessed be!) because of unproven, assumed evolutionary ancestors. No, old son, it's common design, not common origin. Use your intelligently designed mind to see the work of the Creator.
During all these alleged millions upon millions of years there has been no change in these animals, while sub-human creatures became man, dinosaurs evolved into birds, and a group of mammals even returned to the oceans to become whales. Is it not strange that mutations and natural selection have not affected the horseshoe crab for all this supposed deep evolutionary time? Creation scientists maintain horseshoe crabs have always been horseshoe crabs since their creation thousands of years ago—that’s why the fossils match the living creatures. 
Today, these post-Flood creatures are literally keeping people healthy with their uniquely designed blue opaque blood. Medical science has discovered that horseshoe-crab blood is very sensitive to contamination, such as bacterial toxins.
