Luzia woman is an 11,500-year-old funny-looking skeleton found in a cave in Brazil. According to Wiki, “Her facial features include a narrow, oval cranium, projecting face and pronounced chin, strikingly dissimilar to most Native Americans and their indigenous Siberian forebears. 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.
There are a large number (81) of similar skeletons at this site, ranging from around 11,500 to 7,000 years old.
from the PNAS article: “The results obtained from all multivariate analyses confirm a close morphological affinity between SouthAmerican Paleoindians and extant Australo-Melanesians groups, supporting the hypothesis that two distinct biological populations could have colonized the New World in the Pleistocene/Holocene transition.”
This is right in the area where we find the pseudo-Andamanese, Australo-Melanesian genetic signal.
If those skeletons really do look like Australo-Melanesians, it’s not because they carry a 2% admixture. They would have to be mostly Australo-Melanesian. Which means that they got there first.
Since there are so many skeletons of this kind, there should a fair chance that at least one will have useable DNA, particularly since we’re getting better aDNA recovery.
I wonder if this isn’t already underway.
