Q: School starts in 2 days man can you explain to me how the ice age affected south american tribes/groups such as the incans or aztecs migrate? I don't understand as wouldn't they be there before the Ice Age not like they came from the huge ice bridge right?
A: the general idea is that ANYONE in north or south america (before the europeans) came through beringia/alaska. over time they spread out, all the way down to south america. although some people look at the olmec statues and insist that they are african but i think that is widely believed to not be true
