New anthropological research proves that our early ancestors Lucy and Selam climbed trees. So what, and what does that mean for humans?Lucy and Selam are famous skeletons that belong to Australopithecus afarensis, a direct ancestor of humans that lived between 4 and 3 million years ago. In this Pritzker lecture, Dr. Zeray Alemseged, Irvine Chair and Curator of Anthropology at the Academy, discusses the evidence for climbing behavior in A. afarensis based on new evidence from his own find "Selam," currently the most complete and earliest skeleton of a juvenile human ancestor.
