Hominid ancestor: Humans and Chimpanzees had a common ancestor that lived in Africa about 7 million BCE. Humans did not evolve from Chimpanzees, but both are the current evolution of a common ancestor. That common ancestor has yet to be identified and is sometimes referred to as the Chimpanzee–Human Last Common Ancestor (CHLCA). That common ancestor lived sometime between 5 and 25 million BCE with 7 million BCE being a common “best guess”. The living species that evolved from this common ancestor are gathered together in the Hominini family — the scientific taxonomic tribe. The only living species on Earth that are part of the Hominini family today are humans and two types of Chimpanzees: common and bonobo. All the other species that evolved from our common ancestor are now extinct.
