RFLP analysis of mtDNA from six platyrrhine genera: phylogenetic inferences

Abstract

This study investigates the phylogenetic relationships of 10 species of platyrrhine primates using RFLP analysis of mtDNA. Three restriction enzymes were used to determine the restriction site haplotypes for a total of 276 individuals. Phylogenetic analysis using maximum parsimony was employed to construct phylogenetic trees. We found close phylogenetic relationships between Alouatta, Lagothrix and Ateles. We also found a close relationship between Cebus and Aotus, with Saimiri clustering with the atelines. Haplotype diversity was found in four of the species studied, in Cebus albifrons, Saimiri sciureus, Lagothrix lagotricha and Ateles fusciceps. These data provide additional information concerning the phylogenetic relationships between these platyrrhine genera and species.
