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. [20]
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.
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).
These are proposed species names for fossils from about 1.9–1.6 Ma, whose relation to Homo habilis is not yet clear. 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 ...
A phylogenetic analysis published in 2017 suggests that H. floresiensis was descended from a species (presumably Australopithecine) ancestral to Homo habilis, making it a "sister species" either to H. habilis or to a minimally habilis-erectus-ergaster-sapiens clade, and its line is older than H. erectus itself.

The category archaic human lacks a single, agreed definition. [11] According to one definition, Homo sapiens is a single species comprising several subspecies that include the archaics and modern humans. Under this definition, modern humans are referred to as Homo sapiens sapiens and archaics are also designated with the prefix "Homo sapiens".
Homo ergaster is an extinct species or subspecies of archaic humans who lived in Africa in the Early Pleistocene.Whether H. ergaster constitutes a species of its own or should be subsumed into H. erectus is an ongoing and unresolved dispute within palaeoanthropology.
