A Cleveland Museum of Natural History official has been credited with finding a pre-human species. Curator of Physical Anthropology Doctor Yohannes Haile-Selassie discovered the fossil of a pre-human jawbone in Ethiopia that is at least three-and-a-half-million-years old. The discovery of the new species called Australopithecus Deyiremeda is being hailed in the journal "Nature" as one of the biggest since "Lucy" (Australopithecus Afarensis) was found in the 1970s.
