When the bones of two early humans were found in 1967 near Kibish, Ethiopia, they were thought to be 130,000 years old.A few years ago, researchers found 154,000- to 160,000-year-old human bones at Herto, Ethiopia.Now, a new study of the 1967 fossil site indicates the earliest known members of our species, Homo sapiens, roamed Africa about 195,000 years ago.hey conclude the fossils are much older than a 104,000-year-old volcanic layer and very close in age to a 196,000-year-old layer, says Brown. These are the oldest well-dated fossils of modern humans (Homo sapiens) currently known anywhere in the world, the scientists say in a summary of the study.
