Searching for humanity's roots: Zeresenay Alemseged on TED.com

Zeresenay “Zeray” Alemseged has been digging the badlands of Ethiopia, looking for clues to humanity’s origins. Here he talks about one of his most exciting finds: the 3.3-million-year-old bones of Selam, a 3-year-old hominid child, from the species Australopithecus afarensis. In studying Selam’s tiny bones, Alemseged is searching for the points at which we humans became human. (Recorded June 2007 in Arusha, Tanzania. Duration: 16:08.)
