Scientists Find 3.6 Million-Year-Old Relative of 'Lucy'

Scientists have announced the discovery of a 3.6 million-year-old partial skeleton found in Ethiopia, with the early hominid believed to be 400,000 years older than the famous "Lucy" skeleton.
The scientists say research on this new specimen indicates that advanced human-like, upright walking occurred much earlier than previously thought.
The discovery and analysis was carried out by a team of international scientists from The Cleveland Museum of Natural History, Kent State University, Case Western Reserve University, Addis Ababa University and Berkeley Geochronology Centre .
They say the partial skeleton belongs to "Lucy's" species, Australopithecus afarensis.

Human-Like Walking is Ancient

Meet "Lucy's" Great-Grandfather. Cleveland Museum of Natural History Curator and Head of Physical Anthropology Dr. Yohannes Haile-Selassie led an international team that discovered and analysed a 3.6 million-year-old partial skeleton found in Ethiopia. The early hominid is 400,000 years older than the famous "Lucy" skeleton and is significantly larger in size. Research on the new specimen reveals that advanced human-like, upright walking occurred much earlier in the evolutionary timeline than previously thought. Haile-Selassie is the first author of the initial analysis of the specimen, which will be published in the online early edition of the Proceedings of the National Academy of Sciences during the week of June 21, 2010.
