Homo (from Latin homō '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
The genus Homo has been taken to originate some two million years ago, since the discovery of stone tools in Olduvai Gorge, Tanzania, in the 1960s. Homo habilis (Leakey et al., 1964) would be the first "human" species (member of genus Homo) by definition, its type specimen being the OH 7 fossils.
Human evolution is the evolutionary process that led to the emergence of anatomically modern humans, beginning with the evolutionary history of primates – in particular genus Homo – and leading to the emergence of Homo sapiens as a distinct species of the hominid family, the great apes.
Homininae (the hominines), is a subfamily of the family Hominidae (hominids). (The Homininae— / h ɒ m ɪ ˈ n aɪ n iː / —encompass humans, and are also called "African hominids" or "African apes".) [1] [2] This subfamily includes two tribes, Hominini and Gorillini, both having extant (or living) species as well as extinct species.
LD 350-1 is the earliest known specimen of the genus Homo, dating to 2.75–2.8 million years ago (mya), found in the Ledi-Geraru site in the Afar Region of Ethiopia.The specimen was discovered in silts 10 m (33 ft) above the Gurumaha Tuff section of the site [1] [2] by Ethiopian palaeoanthropologist Chalachew Seyoum on 29 January 2013.

The period that followed was marked by a strong increase in cranial capacity, promoting speculation that the loss of the gene may have removed an evolutionary constraint on brain size in the genus Homo. [21] Another estimate for the loss of the MYH16 gene is 5.3 million years ago, long before Homo appeared. [22]
