Molecular evolution of taste perception
Research in my lab is focused on two questions: 1) How have demographic history and natural selection interacted to shape genetic diversity in humans and other primates?, and 2) What are the phenotypic and health implications for populations today? We address these questions by using theoretical and computational tools to detect signatures of evolutionary change in DNA sequences and genotypes.
A major emphasis for us is on the molecular evolution of taste perception. Taste perception plays a vital role in animal nutrition and health. By enabling the detection of nutrients and toxins in foods and other substances in the environment, taste enables response: consumption or avoidance. The importance of this role to fitness suggests that taste perception and its underlying mechanisms have been under intense selective pressures throughout the course of human evolution. We investigate these pressures by analyzing genetic diversity in taste receptors, functional variation, and perception in humans, chimpanzees, and other primates.
