Abstract : Here we report datings of a hominid cranium (specimen KNM-ER 3884) and femur (KNM-ER 999) from the Lake Turkana region, Kenya, that indicate ages of around 270,000 and 300,000 years, respectively. These hominids might represent the oldest near-modern human specimens from anywhere in the world. Our datings and other recent evidence indicate that the chronological framework of Homo sapiens evolution in Africa needs to be revised.
