Professor Holliday received his B.A. in anthropology from Louisiana State University in 1988, and his M.A. (1991) and Ph.D. (1995) in anthropology from the University of New Mexico. A paleoanthropologist, he studies fossil hominins from a host of different time periods. He is particularly interested in the origins of modern humans (Homo sapiens), a topic which is intimately tied to the question of the fate of the Neandertals (H. neanderthalensis). He is also interested in late Australopithecus and the origins of the genus Homo, and in interspecific hybridization among extant mammals and its implications for human evolution. Professor Holliday teaches courses in human evolution, functional morphology, and modern human adaptation and variation.
