Homo erectus is the most long-lived species of Homo, having survived for almost two million years. By contrast, Homo sapiens emerged about a third of a million years ago. Regarding many archaic humans , there is no definite consensus as to whether they should be classified as subspecies of H. erectus or H. sapiens or as separate species.
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.
Leakey named it "Chellean Man", in reference to the Oldowan tools found at the site, which were then referred to by the now-obsolete name Chellean.Heberer (1963) provisionally named a new species Homo leakeyi based on the specimen in honor of Leakey, [3] but most subsequent workers have regarded it as Homo ergaster, or as Homo erectus (H. ergaster is sometimes regarded as a subspecies of H ...
Homo heidelbergensis (also H. erectus heidelbergensis, [1] H. sapiens heidelbergensis [2]) is an extinct species or subspecies of archaic human which existed from around 600,000 to 300,000 years ago, during the Middle Pleistocene.
Moreover, in 2005, a new complete skull cranium was found: D4500. This cranium is inferred to be an adult skull and is more commonly known as "Skull 5." D4500's features are very rare compared to early Homo in that it had a small braincase yet an unusually large prognathic face. [2] "Skull 5" has an accompanying mandible, D2600, which was found ...
Homo rudolfensis refers to a single, incomplete skull from Kenya. Scientists have suggested that this was a specimen of Homo habilis, but this has not been confirmed. [64] Homo georgicus, from Georgia, may be an intermediate form between Homo habilis and Homo erectus, [65] or a subspecies of Homo erectus. [66]

Peking Man characterises the "classic" H. erectus anatomy. The skull is long and heavily fortified, featuring an inflated bar of bone circumscribing the crown, crossing along the brow ridge, over the ears, and connecting at the back of the skull, as well as a sagittal keel running across the midline.
