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).
There is still no wide consensus as to whether or not H. habilis is ancestral to H. ergaster / H. erectus or is an offshoot of the human line, [19] and whether or not all specimens assigned to H. habilis are correctly assigned or the species is an assemblage of different Australopithecus and Homo species.

In Africa in the Early Pleistocene, 1.5–1 Ma, some populations of Homo habilis are thought to have evolved larger brains and to have made more elaborate stone tools; these differences and others are sufficient for anthropologists to classify them as a new species, Homo erectus—in Africa. [71] This species also may have used fire to cook meat.
Homo erectus (/ ˌ h oʊ m oʊ ə ˈ r ɛ k t ə s / lit. ' upright man ') is an extinct species of archaic human from the Pleistocene, spanning nearly 2 million years.It is the first human species to evolve a humanlike body plan and gait, to leave Africa and colonize Asia and Europe, and to wield fire.
The site has a timeline spanning 2 million to 20,000 years ago, and researchers have uncovered the remains of ancient human ancestors such as Homo habilis, Homo erectus and prehistoric Homo ...
Roughly 2.4 million years ago Homo habilis had appeared in East Africa: the first known human species, and the first known to make stone tools, yet the disputed findings of signs of tool use from even earlier ages and from the same vicinity as multiple Australopithecus fossils may put to question how much more intelligent than its predecessors ...
Homo erectus greatest extent (yellow), Homo neanderthalensis greatest extent (ochre) during Out of Africa and Homo sapiens (red, Out of Africa II), with the numbers of years since they appeared before present. Early human migrations are the earliest migrations and expansions of archaic and modern humans across continents.
Homo habilis could have developed some baseline behavioural flexibility prior to its expansion into the peripheries (such as encroaching into the predatory guild [45] [46]). This flexibility could then have been positively selected and amplified, leading to Homo erectus ' adaptation to the peripheral open habitats. [47]
