Homo rudolfensis

Homo rudolfensis was a species of the genus Homo, existing 1. 9 million years ago, that is homo rudolfensis only through a handful of representative fossils, the first of which was discovered in 1972 at Lake Turkana in Kenya by Bernard Ngeneo, a member of a team led by anthropologist Meave and Richard Leakey. In 2012 Meave Leakey discovered further fossils, consisting of a face and two jawbones . Homo rudolfensis was contemporary with Homo habilis, but it is not yet known if it was ancestral to the later species of Homo.

The two different species may well have interacted. The specimen Skull 1470, upon construction, is ape-like in appearance. Please forward this error screen to 69. The scientific name Pithecanthropus rudolfensis was proposed in 1978 by V. On 8 August 2012, a team led by Meave Leakey announced the discovery of a face and two jawbones belonging to H.

The fossil KNM-ER 1470 was the center of much debate concerning its species. The skull was at first incorrectly dated at nearly three million years old, predating the Homo habilis species. Since then, the estimate has been corrected to 1. In March 2007, a team led by Timothy Bromage, an anthropologist at New York University, reconstructed the skull of KNM-ER 1470. Comparisons between fossil OH 24, recognized as a Homo habilis skull discovered by Peter Nzube, along with the female H. When compared to other older H. OH 24, the mandible and jaw of ER 1470 do not fit within the limits of variation of H. KNM-ER 1470 displays less prognathism and a rounder brain case. Even if sexual dimorphism were considered, the size difference in the mandible and teeth would be too great compared to KNM-ER 1813.

Fossil KNM-ER 1470, a male H. KNM-ER 1813 and portrays a much larger brain case than KNM-ER 1813. When KNM-ER 1813 and KNM-ER 1470 are compared to OH 24, similarities between OH 24 and KNM-ER 1813 are more widely evident than with KNM-ER 1470. In August 2012, a team led by Meave Leakey published an academic paper in Nature announcing three additional H. Kenya had been found: two jawbones with teeth and a face. The fossils were dated to about two million years ago, being contemporaneous with H.

The differences between KNM-ER 1470 and KNM-ER 1813 can be interpreted in various ways. IT governance structure at The University of Texas at Austin. Public Event: I Came From Where?

Homo , in addition to Homo erectus, in the early Pleistocene of eastern Africa”. Discoveries at Dmanisi, Georgia, which had diverse physical traits and differences in tooth wear, suggest that all the contemporary groups of early Homo in Africa, including Homo ergaster, Homo habilis, and Homo rudolfensis are of the same species and should be assigned to Homo erectus.
