Homo sapiens (Linneaus 1758) extant ~2-3 m tall. After the string of evolutionary steps beginning with Gephyrostegus, there is not much left to produce Homo sapiens, the human being from its predecessor, Australopithecus. Humans have an enlarged braincase, reduced temporal openings, a reduced snout, a prominent forehead, smaller teeth, a chin, smaller mandible. The arms are shorter and the legs are longer.

Homo floresiensis (Brunet et al 2004) stands about 1 m tall and has primitive feet.
