Craniofacial comparisons between the earliest and latest human skeletons of America have suggested the existence of a complex scenario underlying the biological evolution of American populations. Particularly, these studies proposed migratory processes -physical movement of large number of people ac...

The early samples were compared against Late Holocene samples, showing pronounced differences. The analyzed samples present the greatest morphological variation when plotted with other early American samples. However, using solely cranial morphometric differences it is hard to support the hypotheses that morphological variations between early and late American samples are related to migratory processes or other factors.
