Virginia Commonwealth University anthropology professor Amy Rector Verrelli, Ph.D., just returned from a research trip to Ethiopia where she served as part of the Ledi-Geraru Research Project that in 2013 discovered a fossil of the earliest member of the genus Homo, pushing back the origin of humans’ genus to 2.8 million years ago.
Rector Verrelli, an assistant professor of anthropology in the School of World Studies in the College of Humanities and Sciences, was one of a team of researchers from Arizona State University, Pennsylvania State University, George Washington University and the University of Nevada, Las Vegas hunting for fossils in the Afar region of Ethiopia, between the Ledi and Geraru rivers.
“It has deposits that are between about 1 million and 3 million years ago, so the goal is to look for fossils of our ancestors from that time period,” Rector Verrelli said. “In that area, that usually means Australopithecus afarensis (famous for the Lucy skeleton), but in 2013 project scientists discovered the earliest member of our genus, the genus Homo.”
Researchers in 2013 found a partial hominin mandible with teeth from the Ledi-Geraru research area, thereby establishing the presence of Homo between 2.8 million and 2.75 million years ago. The find extended the record of recognizable Homo by at least a half-million years, shedding new light on human evolution.
