Abstract: The earliest humans just got earlier Thirty-five years ago, papers in Nature by Richard Leakey and colleagues described fossils from the Kibish Formation, southern Ethiopia, attributed to Homo sapiens. These fossils are important to hypotheses concerning our African ancestry, and were believed to be about 130,000 years old. Recent finds from Herto, also in Ethiopia, put the date of the earliest modern humans back to around 160,000 years ago. But now a reappraisal of the Kibish sediments suggests that they are much older than was thought, putting the date of the human remains back to 195,000 years ago.
