The Perry Lab at Western University focuses on primate evolution with a particular emphasis on the interplay between chewing apparatus and diet. By studying the gross anatomy and fiber architecture of jaw-closing muscles, the lab seeks to understand how muscle dimensions correlate with body size and diet among primates and other mammals. Paleontological field studies in the Americas provide insights into the historical context of primate evolution and responses of primates to ecological crises. The lab also conducts experimental research on the biomechanics of the primate skull, examining leverage and excursion in the chewing system. Additionally, they explore ecological changes in mammalian communities during significant climatic events and assess the material properties of food through experimentation that includes simulated food breakage by primate molars. This multifaceted approach makes meaningful contributions to our understanding of primate paleobiology.
