Changes in skull components of the squirrel monkey evoked by growth and nutrition: an experimental study.

abstract：:The movement of humans into the Americas remains a major topic of debate among scientific disciplines. Central to this discussion is ascertaining the timing and migratory routes of the earliest colonizers, in addition to understanding their ancestry. Molecular studies have recently argued that the colonizing populatio...
