A Quote by Carl Edward Sagan on evolution, transition, human animal, creation, and carl sagan

We are the product of 4.5 billion years of fortuitous, slow biological evolution. There is no reason to think that the evolutionary process has stopped. Man is a transitional animal. He is not the climax of creation.

Carl Sagan (1934 - 1996)
