Human fossils found 38 years ago in Africa are 65,000 years older than previously thought, a new study saysâ€”pushing the dawn of "modern" humans back 35,000 years.
New dating techniques indicate that the fossils are 195,000 years old. The two skulls and some bones were first uncovered on opposite sides of Ethiopia's Omo River in 1967 by a team led by Richard Leakey. The fossils, dubbed Omo I and Omo II, were dated at the time as being about 130,000 years old. But even then the researchers themselves questioned the accuracy of the dating technique.
The new findings, published in the February 17 issue of the journal Nature, establish Omo I and II as the oldest known fossils of modern humans. The prior record holders were fossils from Herto, Ethiopia, which dated the emergence of modern humans in Africa to about 160,000 years ago.
