Biogeography of New World Monkeys

Show Summary Details

Preview

The eight widespread clades of New World monkeys are examined, and the distributional breaks in the clades are compared. The breaks and overlaps are related to the Cretaceous and Cenozoic tectonics of the region. Overlap among the main clades is attributed to Cretaceous marine incursions, while overlap among lower-level clades may reflect Miocene marine seas. Phylogenetic breaks are related to tectonic events, including the uplift of the Andes and the failed rifting along the Amazon, which themselves were caused by the opening of the Atlantic. Maximum primate diversity in western Amazonia is attributed to the same foreland basin tectonics that produced belts of major oil fields in the region.
