The Buried Truth About Aboriginal Australian Origins

Did ancient Australians inherit ancestry from the Homo erectus populations of Java? Alan Thorne argued that similarities between Australian and Indonesian skulls pointed toward regional continuity. We explore his controversial theory, confirmed Denisovan interbreeding, and newer evidence suggesting an even deeper Asian contribution to human ancestry.
