The only living species is ''[[Homo sapiens]]'' (humans). The genus began about 2.3 million years ago. Their ancestors were almost certainly some line of [[Australopithecine]] apes. Species of ''Homo'' have: #A larger brain (above 900ml) #Improved walking and running ability. As the process continues, the forehead becomes more [[vertical]], the skull becomes rounder, the teeth are reduced in size, arms are shorter and legs are longer. The skeleton becomes more delicate. particularly in our species. All species used [[stone tools]], but there is no evidence of when [[language]] developed.
