There are New World monkeys, but no New World apes except us. I understand that the oldest Old World signs, cave paintings and cave art items, may be 70,000 years old. It would be interesting if something like that is found in the New World, but what about that 200,000 year old stuff in California?

I'll guess they were Homo-Erectus?
