Now that we have the small detail of EVIDENCE out of the way, we can really start to get somewhere with Cofty's thread.
Let's see if we can invent a story that applies Cofty's evolutionary principles to the caterpillar:
Once, there was nothing. Then nothing happened to the nothing and everything appeared. But the everything was a mess and disorganized. Then, two rocks bumping together in water produced a chemical reaction at the same time that lightning struck it. For no apparent reason, the chemical reaction was agreeable to itself and it decided to do it again and again. The principle of replication was thus introduced to the primordial soup and after billions of years and trillions of attempts, the first replicating cell was formed that required thousands of interdependent parts and chemical reactions to accidentally appear at the exact same time, at the molecular level for no reason.
Likewise, the first cell also found itself agreeable to it's own existence and so it decided to replicate itself in accordance with the principle of self-replication long established in the chemical laden primordial soup. In order to do this, an information containment system was needed to contain the information required to accomplish such a feat for the thousands of interdependent parts and processes needed for the cell to function. So a double helix protein was invented to hold such information. Then a four letter coding system was selected among thousands of candidates to efficiently carry the information, that if stacked like the pages of a book, would reach more than 3/4 to the moon.
Eventually after eons of time and "millions of years", the cells themselves realized that if they worked together they could assimilate themselves into complex organisms that could better compete for limited resources.
After many more millions of years, the caterpillar appeared. It fed off the rich vegetation of a primitive landscape. Time after time the caterpillar tried to reach too far from the branch only to fall to the ground in defeat. Eventually, it learned that if it made itself gooey and sticky it could travel farther out on a branch without falling. Yet, eventually it ran out of leaves to eat once they were gone.
Already existing in a semi gooey state, the caterpillar increased this process until it digested nearly all of itself with enzymes. Yet part of the original caterpillar remained in the goo. The part that remained, "remembered" how it felt to be so far out on a limb that all resources had been exhausted.
Seeking to move away from this discomfort, and toward a place of stasis - the coding began to organize itself over millions of years to include the ability of flight. This allowed the organism, when it found itself too far out on a limb, to simply fly away to live another day - just like Cofty.
