Primate Evolution

Non-human primates as models for hominin evolution

Many hominin lineages speciated through the Pliocene and Pleistocene. However, with the exception of Homo sapiens, all are extinct today, limiting avenues of investigation into their evolutionary history. I therefore use primate groups with many extant species as models for examining various aspects of the hominin radiation. For example, my research has revealed significant Y-chromosomal exchange between modern primate lineages, and uncovered genetic patterns consistent with the notion of “hybrid origin” species. Such findings suggest, by comparison, that hybridization may have been a significant mechanism in hominin evolution, and highlight the possibility of chimeric ancestral hominin forms. Other research addresses topics such as the origins of terrestriality, identification of new species, and primate biogeography.
