I've been doing a little research on primates in N. America, just to expand my knowledge base. I like to make sure I understand what I read correctly.
From what I understand, 50 million years ago, the earth was a lot warmer than it is today. Most of N. America was covered in tropical rain forest. There's even evidence of palm trees growing in Alaska at the time. During this period there quite a few species of primates that lived in N. America.
Then about 33 million years ago, a new ice age started, which caused global temperatures to drop dramatically. So dramatically it caused a "Mass Extinction Event". None of the primate species of N. America were able to adapt to the new climate, so they either went extinct or migrated south the equatorial S. America...leaving no primate species in N. America at all.
It wouldn't be until 20 million years ago that the first of the great apes evolved in Africa and Asia...and there is no fossil evidence that they ever migrated to either N. or S. America...nor did great apes evolve in S. America.
So from what I gathered, there's never been great apes in the Americas ever. I just want to make sure I'm understanding this correctly. I also was unable to find any examples of great apes that adapted to live in colder climates...did I miss any?
Not according to any practical, empirical, non-anecdotal, objective evidence.
