The peopling of the Americans as viewed from South America

Examination of data from Brazilian prehistoric remains, anthropometric variation and genetic polymorphisms of Brazilian or South American Indians in general do not furnish clues about the routes travelled by the first colonizers within the continent. Although the main contribution for the Amerindian gene pool should have originated in Siberia, the genetic data do not contradict the possibility of other, minor sources from the Pacific (Proto-Polynesians ?).
