Evolutionary History of the Robust Australopithecines

Frederick E. Grine is professor and chairperson in the department of anthropology at the State University of New York at Stony Brook. He has published many scientific articles in books and international journals, and he is co-editor of Primate Phylogeny and Scanning Microscopy of Vertebrate Mineralized Tissues and author of Regional Human Anatomy.
