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?
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
