And why would the ancestor of humans, or any other creature, not survive along with the differing branches that evolved from it?
Kind of like the answer in the form of a question, *If Americans came from Europeans, then why are there still Europeans?*.
Funny how the evos want to have their cake and eat it to.
On the European vs. American question Darwin said it had been demonstrated that Europeans had bigger brains so maybe according to Darwinism Americans are devolved, And I suppose he'd get no argument in Europe.
