Did you see the recent DNA research that links Amazonian Amerindians to Australian Aboriginals? I wonder how extensive that link really is? I’m assuming the majority of Amerinds are mostly related to the Siberian migration.

It’s not as crazy as it sounds. The very first people to the Americas were Australoids. On skulls, they would resemble Aborigines, as Aborigines are Australoids. The early Amerind skulls look Australoid. Some look like Melanesians or Ainu. Melanesian and Ainu skulls are Australoid. As the early Amerinds came from the north, perhaps the early Amerinds were linked to the Ainuids. We know that skulls from NE Asia before 9,000 YBP look like Aborigines.

I am not sure what the link between Amazonian Indians and Aborigines is. Is it on genes or on skulls? Can someone link me to this stuff?
