From Wikipedia: Anthropologists have variously described Luzia's features as resembling those of Negroids, Indigenous Australians, Melanesians and the Negritos of Southeast Asia. Walter Neves,
an anthropologist at the University of São Paulo, suggests that Luzia's
features most strongly resemble those of Australian Aboriginal peoples.
Dear Corley Walsh,
You are doing some really interesting study...the YouTube you found was very interesting...and I located a NY Times article that suggests the connection with the Australians. These folks speculate that Negroid peoples were in SE Asia, from whence some went to Australia (ancestors of the aborigines) and others to the Americas.

Also found a photo of Luzia skull for you! Also came across a reconstruction...she was very pretty!
