Just saw a very interesting video on Youtube. It's about the just discovered South American prehistoric caves full of paintings. Some of the paintings show people hunting Giant Armadillos, that went extinct back in the last Ice Age! Archeologists dug down and found charcoal and animal bones suggesting human occupation over 40,000 years old! They have recovered dozens of intact skulls and discovered via measurements that they were Aboriginal! Apparently, these explorers arrived by boat and colonized South America. When the ice cap melted about 14000 years ago, Siberians could cross the land bridge and colonize from North America southward. When they encountered the Abos, they wiped them out. But they still find some Abo-shaped skulls in recently dead native people down on Tiera Del Fuego.
