Homo erectus (extinct) Homo ergaster (extinct) Homo floresiensis (extinct) Homo habilis (extinct) Homo heidelbergensis (extinct) Homo neanderthalensis (extinct) Homo rudolfensis (extinct) Homo sapiens
Homo is the genus that includes humans and their close relatives. The genus is estimated to be between 1.5 and 2.5 million years old. All species and subspecies except Homo sapiens sapiens are extinct; the last surviving relative, Homo neanderthalensis, died out 30,000 years ago, although recent evidence suggests that Homo floresiensis lived as recently as 12,000 years ago.
A minority of zoologists consider that the chimpanzees (usually treated in the genus Pan) should also be included in the genus.
Homo sapiens (including modern humans, Homo sapiens sapiens)
The last three have been considered to be subspecies of Homo sapiens, but analysis of mitochondrial DNA from H. neanderthalensis fossils suggests that the difference is great enough to count as a separate species.
Homo habilis (IPA /ˈhoʊmoʊ ˈhæbələs/) ("handy man", "skillful person") is a species of the genusHomo, which lived from approximately 2.5 million to 1.8 million years ago at the beginning of the Pleistocene.
Homo habilis was short and had disproportionately long arms compared to modern humans, however it had a reduction in the protrusion in the face.
Homo habilis is thought to be the ancestor of the lankier and more sophisticated, Homo ergaster, which in turn gave rise to the more human-appearing species, Homo erectus.
