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.
Ape skeletons. A display at the Museum of Zoology, University of Cambridge.From left to right: Bornean orangutan, two western gorillas, chimpanzee, human. The evolution of human bipedalism, which began in primates approximately four million years ago, [1] or as early as seven million years ago with Sahelanthropus, [2] [3] or approximately twelve million years ago with Danuvius guggenmosi, has ...
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
In the Late Pliocene, hominins were set apart from modern great apes and other closely related organisms by the anatomical evolutionary changes resulting in bipedalism, or the ability to walk upright. [8] [9] Characteristics such as a supraorbital torus, or prominent eyebrow ridge, and flat face also makes Homo erectus distinguishable.
Homo erectus was the first ancient human to migrate out of Africa about 1.9 million years ago. Although Homo erectus had a gait and body size similar to modern humans, researchers think the ...
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]
While Homo habilis was certainly bipedal, its long arms are indicative of an arboreal adaptation. [60] Homo erectus had longer legs and shorter arms, revealing a transition to obligate terrestriality, though it remains unclear how this change in relative leg length might have been an advantage.
