The two layer hypothesis, or two layer model, argues that Eastern and Southeastern Asia was initially occupied by hunter-gatherer groups considered to be Australo-Papuans before being replaced by Neolithic agriculturalists, who possessed East Asian cranial morphology. Cranial morphometrics and dental characteristics of human remains were cited as evidence for the hypothesis.
