Biological (physical) anthropology focuses on the biological evolution of humans, human fossil ancestors, and non-human primates, as well as the patterns of biological and bio-cultural variation within and among living and fossil human populations. Current faculty research includes: the evolution of craniofacial anatomy in fossil Homo, especially Neandertals and early modern humans from both hominid paleontological and clinical experimental approaches; human evolution in Asia, especially Homo erectus in terms of both geochronological and ecological perspectives; and non-human primate evolution in Asia, especially Gigantopithecus.
