That suggests the New World was peopled by waves of different ethnic groups. DNA testing could confirm or rule out links. But getting a good enough sample from the Kennewick bones has been impossible to date.
Considering this court fight took over a year or more,
I wonder if DNA might have been possible to get if it
had been taken when first discovered.
The evidence is becoming over-whelming.
Luzia, 11,500 years old...found in Brazil.
Yeah, I don't doubt it. It used to be believed that the Americas were peopled around 1000 BC, and it was professional suicide to suggest greater antiquity. When the Clovis finds suggested a much greater age, motion toward that idea was very slow until radiocarbon dating was available, at which point the new date became the new floor under which dates could not fall. I call this Clovis-First-and-Only, and while there are some who still cleave to it, it is dead now.
