Ardi

Ardi is a primitive homonid fossils with scientific name Australopithecus ramidus. It was first found in Ethiopia in 1992, but it took 17 years to assess their significance. Ardi is a more primitive hominid than Australopithecine skeleton, Lucy. Researchers describe this 4.4 million-year-old ancient human creature – nicknamed "Ardi" – that may be a direct ancestor to us. The 17-year investigation of the fossils is named as Science journal’s big breakthrough of 2009.
