An interesting article that contributes to the debate about the "Peopling of the New World"

This study observed the crania of Paleoindians and Archaics from North and South America and compared their observations to a worldwide database. This study also looked at Fst statistics derived from their subjects in order to conclude that the earliest North and South Americans came from an East Asian population. Essentially, it confirmed what scientists already know from looking at fossil records and genomic data - that the "peopling of the new world" involved a migration of a certain sub-population from Eurasia, across some sort of land bridge (now submerged due to the melting of the polar ice caps), to the Americas.
