George Carlin’s question is one of the more stupid ones I have seen. There are still monkeys because there are still trees which are a good place for monkeys to live and not such a good place for humans to live. Creatures evolve to live in specific suitable environments. Today I was reading about Marsupial evolution compared with Mammalian evolution. There are Marsupial anteaters and mammalian anteaters and they both evolved effective strong claws to tear apart termite mounds. Marsupial moles and Mammal moles both are nearly blind and have powerful digging claws. Unlike almost all other Marsupials which have a baby pouch which aims upward, the Marsupial moles pouch aims downward so they don’t scoop dirt into the pouch as they crawl along. Evolution is amazing. If you want more up to date information try reading Shawn Carrol’s “Endless Forms Most Beautiful” which covers some amazing recent discoveries about evolution and species formation. Perhaps Darwin should not have named his book “The Origin of Species”, but rather “The Evolution of Species.” He did not have the technical equipment to examine the very early precambrian development of living entities or of microbiology, so his theories were based on examination of macrolife, not microlife where it all started.

What’s interesting is all the things you point out here could be used as arguments for design as well.
I think this question is still well beyond the scope of science and that’s why it’s so “controversial”.
Contrast to, say, the properties of gold, aren’t particularly controversial.
You are confusing adaptations with evolved species. By your definition a redhead is a different species than a blond person. Where did life come from?
