I'm open to any evidence. I doubt we can find a Chimpanzee that sat, thought about it for awhile, slept on it, and then decided it's time to live like a Bonobo.

I think the best evidence we have are actual metamorphosis that you see from a tadpole over to a frog, things of that sort. We're the only species that can do something to our nature actively.
