The skull shape South American scientist comes up at 2:00 of this video
Pre-columbian introduction of chicken to South America and sweet potato to Polynesia demonstrated Polynesian contact with the Americas well. However, in the show there is an archaeologist, Jose Miguel Ramirez of the University of Valparaíso in Chile, who based some of his assumptions on skull shapes:
Skulls found on Mocha island
Didn't know skull shape anthropology is still a thing...
As a Taiwanese, I have both of these features, especially the pentagonal rare view of the skull thing. I've always thought it's that shape because my parents must had bumped my head when I was a baby or something :P
Since the Dr. Ramirez had large pieces of bones, entire femurs no less, couldn't he just do a DNA test and be done with it, instead of having to compare skull shapes?
