Robert FoleyRobert A. Foley is Director of the Leverhulme Centre for Human Evolutionary Studies at the University of Cambridge. His research is concerned with the pattern of human evolution in terms of evolutionary processes. At one level this relates specifically to the evolution of adaptive behaviours and morphologies during the course of human evolution, in relation to environmental and socioecological context of fossil hominins. At another level it is concerned with the integration of adaptive microevolutionary processes with macroevolutionary patterns (speciation, diversity, and extinction).

adam gordonAdam Gordon is a research postdoctoral fellow at the Center for the Advanced Study of Hominid Paleobiology at George Washington University. His research focuses on the role of sexual selection and resource stress on the evolution of body size and size dimorphism within fossil hominins and living primates, and the study of size and shape variation in the hominin fossil record. He is particularly interested in how various aspects of primate biology (mass, postcranial size, canine size, etc.) differ in their sex-specific response to selective forces.
