title: Amerind taxonomy and testable hypotheses.
abstract: The acceptance of a 30,000 yr B.P. age for Valsequillo sets new parameters for hypotheses of Paleoindian entry into America. A review of Amerind taxonomy defines the early groups as Otamid-Sundadonts. Isolation in America led to an adaptive radiation that has implications for the origin and dispersal of Pithecanthropus.
