A Simple Catapillar

Butterfly, Vindula arsinoe.

I just stumbled accross this site.  I have no idea what else it may be teaching, but I did find this bit that is right on target.

Within this tiny egg, only about an eighth of an inch long, is an entire world of genetic information. It contains the instructions for the construction of the caterpillar with the intelligence it needs to operate all of its organs (eyes, antennae, legs, etc.), to maneuver within its environment, to digest leaves, to avoid predators, to know when and how to molt, to pupate, etc. It contains the instructions for the incredibly complex process of the final molting and formation of the pupa, including the amazing cremaster mechanism. It contains the instructions for the death and dissolution of the caterpillar into a biological soup and the reformation of that soup into a beautiful butterfly. It contains the instructions not only to construct the butterfly in all of its mind-boggling complexity (e.g., its proboscis, its compound eyes, its intricately shingled wings, its sensory organs, its reproductive organs) but also the instructions to create the butterfly’s brain and the intelligence needed to thrive within its environment, to fly, to land, to avoid predators, to find the right plants and flowers, to drink and digest nectar, to keep its cold-blooded metabolism in balance, to reproduce. It contains the instructions for a bewildering multi-thousand mile migration to a place it has never been and in the absence of any earthly guide. It would seem, in fact, that the genetic code within that tiny monarch butterfly egg contains a map of a large part of the earth. And it contains the information for constructing hundreds of copies of itself. If the butterfly evolved, then evolution is miraculous and has the attributes of Almighty God!

If you have fat lips you have evolved?

According to http://www.newscientist.com/article/dn18912-fat-lips-evolve-at-record-speed.html some lake cichlids are evolving new physical features.  The features they list though are just variations within the kind, primarily fat lips.  The article does recognize that rapid change within a kind can occur.  In this case they say features can arise in just ten generations.  We would expect to see this sort of variation that doesn’t require additional intelligence.  This is certainly not an example of evolution as the fish is still a fish and the lips are still lips.  This change is likely a loss of information controlling lip development and other features.
