Fossil discovery rewrites the story of human evolution

Posted on August 17, 2012


The history of human evolution is more complex than previously supposed, according to fossils showing that several species of early man once lived cheek by jowl in the same region of East Africa.

Scientists have excavated three new fossils – a face and two jawbone fragments – indicating that at least two other species of human lived between 1.78m and 1.95m years ago at the same time as our direct ancestors. The discovery emphasises the complicated nature of human evolution, which has been likened to an intricate family tree of related species rather than a simple sequential line of direct descent.

The new fossils were found by a team led by Maeve Leakey of the Turkana Basin Institute in Nairobi and belong to individuals who were markedly different from Homo erectus, which is believed to be the direct ancestor of anatomically modern humans, Homo sapiens.
