Freaks of Evolution Part 1

Who you calling a freak?
Ok, first let me get one thing strait, freaks of evolution aren’t demented biology professors. Freaks of evolution, as I will call them, are strange, and highly unlikely things that evolution is supposed to have done. Kind of like a freak of nature, savey? Of course, the whole idea of pond scum, lightning bolts, and destructive mutations randomly creating any form of life is impossible. But believe it or not, the situation gets worse than that. When it gets worse, it becomes a freak of evolution.

Convergent Evolution
Our first freak began way back when scientists found the need to establish an evolutionary family tree. To do this, they tried to fit every known species back to back in a chart showing their gradual evolution. Of course, the absence of smooth transitions between different types of animals, was what first inspired the phrase, “missing link”, by Darwin’s own admission, missing links are an incredible setback to the entire hypothesis of evolution. Another huge setback, Convergent evolution, has also plagued evolutionary scientists. Convergent evolution is when a similar trait evolves multiple times, in totally separate types of animals. It’s like a tornado causing the random assembly of two 747 jumbo jets instead of one! Whereas evolution is impossible, convergent evolution is double, triple, or even quadruple impossible.

Flight
By far my favorite case of convergent evolution is flight. Think about it, there are actually FOUR separate phylums of animals that have the ability to fly. Birds, Insects, Bats (mammals), and extinct flying reptiles. To an evolutionist, this means that the engineering miracle of flight, (taking humans hundreds of years to develop), randomly happened upon four different creatures, and all of them survived thousands of years of transitional life, before finally gaining all the necessary equipment, and taking to the skies.

How hard is Flight?
As I said above, the ancestors of flying creatures would have had to survive thousands of years while developing flight. For birds, Mammals, and reptiles, I imagine this was especially hard. What happens, for instance, when an eagle loses its ability to fly? It becomes easy prey for hungry predators. Natural selection is a real thing, but in this, and many other cases, it would hinder evolution, not drive it forward. Also, think how hard it was for human engineers to develop flight. As my science book would say “The processes involved are far beyond the scope of this coarse”, there is no way I could explain every design that humans have copied from flying animals. However, here are a few examples.

First, as any fifth grader knows, the shape bird’s wing’s created an aria of high and low pressure, which is what enables them to fly. The Write brother’s success, (as the success of every plane since) was all due to copying this design.

Also, as flight developed, planes got faster and faster, and began experiencing turbulence. Planes would literally shake to pieces during take-offs and landings. Once again, flight engineers turned to the bird. They discovered a little feather that was extended in front of the wing each time the bird took off or landed. Not knowing what this feather did, they closely copied the design and turbulence problems were solved. Years later, with the aid of a super computer, scientists found that the physics behind this simple feather were, once again, “Beyond the scope of this coarse”.

Our final example once again comes from the bird. As airplanes advanced, the material needed to build a plane became stronger and stronger. But, as the material got stronger, the plane got heavier. There was a need for a light material that was still extremely strong. Hollow tubes were used, but they were often not strong enough. So, engineers imitated bird bones, creating tubes with many air pockets, each separated by thin sheets of metal. This structure proved many times stronger, and only slightly heavier.

Common Creator
There are many other examples of convergent evolution that I hope to write about. Each case drives home the fact that evolution is not the explanation for this universe. Convergent evolution is more than just a “freak thing”, or a lucky accident. Convergent evolution screams a testimony to our common creator, not common ancestor.

your example of fight is one of my favorite! my text book uses "beyond the scope of this course" VERY often!
