The early bipeds eventually evolved into the australopithecines and still later into the genus Homo.

Ardipithecus, a full biped, arose approximately 5.6Р’В million years ago. The non-bipedal knuckle-walkers, the gorillas and chimpanzees, diverged from the hominin line over a period covering the same time, so either Sahelanthropus or Orrorin may be our last shared ancestor. The earliest hominin, of presumably primitive bipedalism, is considered to be either Sahelanthropus or Orrorin, both of which arose some 6 to 7Р’В million years ago. Bipedalism Р”В«ipedalism is the basic adaptation of the hominid and is considered the main cause behind a suite of skeletal changes shared by all bipedal hominids. Other significant morphological changes included the evolution of a power and precision grip, a change first occurring in H. The most significant of these adaptations are bipedalism, increased brain size, lengthened ontogeny (gestation and infancy), and decreased sexual dimorphism.The relationship between these changes is the subject of ongoing debate. Environmental (culture) evolution discovered much later during the Pleistocene played significant role in human evolution observed via human transitions between subsistence system.

Human evolution from its first separation from the last common ancestor of humans and chimpanzees is characterized by a number of morphological, developmental, physiological, and behavioral, and environmental changes. The hominoids are descendants of a common ancestor 4.2 Divergence of the human clade from other great apes.Within the superfamily Hominoidea, the family Hominidae (great apes) diverged from the family Hylobatidae (gibbons) some 15РІР‚вЂњ20Р’В million years ago subfamily Homininae (African apes) diverged from Ponginae ( orangutans ) about 14Р’В million years ago the tribe Hominini (including humans, Australopithecus, and chimpanzees) parted from the tribe Gorillini (gorillas) between 8РІР‚вЂњ9Р’В million years ago and, in turn, the subtribes Hominina (humans and extinct biped ancestors) and Panina ( chimpanzees) separated 4РІР‚вЂњ7Р’В million years ago. Genetic studies show that primates diverged from other mammals about 85Р’В million years ago, in the Late Cretaceous period, and the earliest fossils appear in the Paleocene, around 55Р’В million years ago. The study of human evolution involves several scientific disciplines, including physical anthropology, evolutionary anthropology, primatology, archaeology, paleontology, neurobiology, ethology, linguistics, evolutionary psychology, embryology and genetics.

This process involved the gradual development of traits such as human bipedalism and language, as well as interbreeding with other hominins, which indicate that human evolution was not linear but a web. Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family, which includes the great apes.
