mate variablity, looking at decade/century-scale climate variability over recent millennia as well as linkages between vegetation changes and climate changes. Dr. Kutzbach is a fellow of the American Geophysical Union and the American Meteorological Society. Some of his awards include the Revelle Medal of the American Geophysical Union and the Milankovitch Medal of the European Geophysical Society. He has B.A., M.A., and Ph.D. degrees from the University of Wisconsin at Madison.

Richard Potts is a paleoanthropologist and director of the Human Origins Program and curator of anthropology at the National Museum of Natural History, Smithsonian Institution. His research focuses on the history of the interrelationships between human evolution and the ecosystem. Over the past decade, Dr. Potts has led excavations at early human sites in the East African rift valley, and currently directs a multidisciplinary research team at the handaxe site of Olorgesailie, Kenya. In addition to research articles and books, he has recently completed a book for a general audience titled Humanity’s Descent: The Consequences of Ecological Instability. In addition, Dr. Potts was awarded a Certificate of Honor by the Academy of Television Arts and Sciences for the Emmy-winning Tales of the Human Dawn on PBS. He has a B.A. in anthropology from Temple University and a Ph.D. in biological anthropology from Harvard University.

Kaye E. Reed is associate director and associate professor in the School of Human Evolution and Social Change of the Institute of Human Origins at Arizona State University. Dr. Reed’s main research focus is the ecological context of primate and hominin evolution, based on using the identification and analysis of mammalian faunas from Plio-Pleistocene hominin localities. Her current field research focuses on early hominin sites (Australopithecus afarensis and early Homo) in the Afar Region of Ethiopia and Neanderthal and modern human cave localities in Spain and Morocco. She earned her Ph.D. from the State University of New York at Stony Brook. Dr. Reed resigned from the committee in May 2009 to accept a secondment position at the National Science Foundation.

Alan R. Rogers is a professor of anthropology and adjunct professor of biology at the University of Utah. Dr. Rogers’ research focuses on using genetic data to understand the history of human population size, based on developing new statistical methods to detect population size changes using sequence data. This largely focuses on understanding the huge population increase of early humans in the late Pleistocene. Additionally, his research interests include the adaptive evolution of such traits as menopause and human time preference. In 1991, the University of Utah recognized Dr. Rogers’ work with their Superior Research Award. He was a former associate editor of Molecular Biology and Evolution. He received a B.A. in anthropology from the University of Texas at Austin and M.S. and Ph.D. degrees in anthropology from the University of New Mexico.
