Homo habilis - KNM-ER 1470

KNM-ER 1470, Homo habilis (or H. rudolfensis)

Discovered by Bernard Ngeneo in 1972 at Koobi Fora in Kenya. Estimated age is 1.9 million years. This is the most complete Homo habilis skull known. Its brain size is 750 cc, large for H. habilis. It was originally dated at nearly 3 million years old, a figure that caused much confusion as at the time it was older than any known australopithecines, from whom H. habilis had supposedly descended. A lively debate over the dating of 1470 ensued. The skull is surprisingly modern in some respects. The braincase is much larger and less robust than any australopithecine skull, and is also without the large brow ridges typical of Homo erectus. It is however very large and robust in the face. A number of leg bones were found within a couple of kilometers, and are thought to probably belong to the same species.
   In the last few years, an increasing number of scientists have been classifying this skull as Homo rudolfensis. Creationists seem to be fairly evenly divided on whether 1470 is an ape or a human.
