Compared to earlier Homo, H. erectus has smaller teeth, thinner enamel, and weaker mandibles (jawbone), likely due to a greater reliance on tool use and food processing. [52] The brain size of H. erectus varies considerably, but is generally smaller in H. erectus sensu lato, as low as 546 cc (33.3 cu in) in Dmanisi skull 5. [53]
[19] [20] One proposal divides Homo erectus into an African and an Asian variety; the African is Homo ergaster, and the Asian is Homo erectus sensu stricto. (Inclusion of Homo ergaster with Asian Homo erectus is Homo erectus sensu lato.) [21] There appears to be a recent trend, with the availability of ever more difficult-to-classify fossils ...
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
Homo (from Latin homÅ 'human') is a genus of great ape (family Hominidae) that emerged from the genus Australopithecus and encompasses only a single extant species, Homo sapiens (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include Homo erectus and Homo neanderthalensis.
Reconstructed skeleton of Tautavel Man. The reconstructed skull of Tautavel Man (based on Arago 21 and 47) shares many similarities with that of H. erectus s. s. These include: strongly defined brows, a receding forehead, a relatively low face, a depression between the eyebrows, post-orbital constriction, strongly defined ridges below the eye sockets, a weak chin (with developed prognathism ...
H. heidelbergensis is closely related to Homo rhodesiensis (also identified as Homo heidelbergensis sensu lato or African H. heidelbergensis), known to be present in southern Africa by 0.3 Ma. Homo sapiens emerges in Africa before about 0.3 Ma from a lineage closely related to early H. heidelbergensis . [ 29 ]
He named the hominin Pithecanthropus erectus (erect ape-man), which has now been reclassified as Homo erectus. In the media, the Java Man was hailed as the missing link. For instance, the headline of the Philadelphia Inquirer on February 3, 1895, was "The Missing Link: A Dutch Surgeon in Java Unearths the Needed Specimen".
About 350,000 years ago a genome of an "erectus-like" creature was injected into the Denisovan lineage. With the separation time of about 2 Ma ago and interbreeding that happened 350 ka ago, the two populations involved were more distantly related than any pair of human populations previously known to interbreed.
