Thus, this edition marks 40 years of continuous publication of The Papers by the Kroeber Anthropological Society, the oldest student-run anthropology organization in the United States. The publication of The KAS Papers has been and continues to be entirely carried out by the volunteer effort of graduate students at Berkeley, and is supported by the resources of the stu- dents and the members of the Society. The papers published in this edition of The Kroeber Anthropological Society Papers are devoted solely to topics within the subfield of physical anthropology. All the authors are connected to the Department of Anthropology at the University of California, Berkeley in some way, be it as recent bachelor's candidates, current graduate students or recent Ph.D.'s. The articles provide a sampling of the latest research being done in physical anthropology at Berkeley; however, they are not meant to completely represent the spectrum of work being performed here. Topics covered in this edition include hominid evolution, primate socioecology, biomedical anthropology, primate dental metrics, sociobio- logy, osteology and primate evolution. The last time The KAS Papers published any articles concerning physical anthropology was in 1977, when, like now, an entire edition was devoted to the subject. Several of the authors of that edition have gone on to successful careers in physical anthropology. Before 1977, less than a dozen physical anthropology articles had been published in The KAS Papers, out of a total of almost 300 papers. This edition is an effort to rectify this historically grievous condition. -- Katherine L. Dustin, Editor
