The first member of the genus Homo to be hairless was Homo erectus, originating about 1.6 million years ago. [6] The dissipation of body heat remains the most widely accepted evolutionary explanation for the loss of body hair in early members of the genus Homo, the surviving member of which is modern humans.

The Dmanisi skull, also known as Skull 5 or D4500, is one of five skulls discovered in Dmanisi, Georgia and classified as early Homo erectus.Described in a publication in October 2013, it is estimated to be about 1.8 million years old and is the most complete skull of a Pleistocene Homo species, [1] [2] and the first complete adult hominin skull of that degree of antiquity.
Homo erectus derives from early Homo or late Australopithecus. Homo habilis , although significantly different of anatomy and physiology, is thought to be the ancestor of Homo ergaster , or African Homo erectus ; but it is also known to have coexisted with H. erectus for almost half a million years (until about 1.5 Ma).
[1] [2] It was initially considered Homo cepranensis, Homo erectus, or possibly Homo antecessor; but in recent studies, most regard it either as a form of Homo heidelbergensis sharing affinities with African forms, [3] [4] or an early morph of Neanderthal.
The extinct species Homo floresiensis has long puzzled experts. A new analysis offers clues to the mystery of this tiny oddball’s place on the human family tree.
