Old World vs New World Primates
Date: Summer 2013
How are there animals like the New World Monkeys which live in S.A. be so similar to their old world counterparts, when they seemingly evolved after the continents split? Could they have maybe crossed on leaf mats or rafts after a tsunami?
Thanks for the questions. I think there are no primates in North America for two reasons. First, the climate is not favorable. Primates require a rain forest and there are few areas which would qualify as a rain forest in North America. Second, the human influence in North America would have easily driven away any primates. I do not know how the New World Monkeys in South America could be so similar to the Old World Monkeys. Perhaps there was a migration?
I hope this helps. Please let me know if you have more questions.
