Humans evolved on the African savannah during the [[Pliocene]] and [[Pleistocene]] epochs. Bipedalism was one of the first traits that our ancestors developed. This occured around 4 million years ago. The recovered remains of "Lucy" (''Australopithecus afaranis'') indicate that the Australpithecines had developed bipedalism before developing into ''Homo'' contrary to popular depictions of cavemen as not being fully bipedal. About 2.5 million years ago at the Plio-Pleistocene boundary the first ''Homo'' appeared. ''Homo habilus'' was believed to be the first hominid to use stone tools but it was later discovered that Paranthropus (aka the "Robust Australpithicines) also used the same primitive stone technology known as Oldowan culture, as ''Homo habilus''. | Humans evolved on the African savannah during the [[Pliocene]] and [[Pleistocene]] epochs.
