Species close to the last common ancestor of gorillas, chimpanzees and humans may be represented by Nakalipithecus fossils found in Kenya and Ouranopithecus found in Greece. Molecular evidence suggests that between 8 and 4 million years ago, first the gorillas, and then the chimpanzees (genus Pan ) split off from the line leading to the humans.
The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage. For the earlier history of the human lineage, see Timeline of human evolution#Hominidae , Hominidae#Phylogeny .
A study of four mammalian genera: Hyopsodus, Pelycodus, Haplomylus (three from the Eocene), and Plesiadapis (from the Paleocene) found that—through a large number of stratigraphic layers and specimen sampling—each group exhibited, "gradual phyletic evolution, overall size increase, iterative evolution of small species, and character ...
Multiregional evolution holds that the human species first arose around two million years ago and subsequent human evolution has been within a single, continuous human species. This species encompasses all archaic human forms such as Homo erectus , Denisovans , and Neanderthals as well as modern forms, and evolved worldwide to the diverse ...
Stone tools found at the Shangchen site in China and dated to 2.12 million years ago are considered the earliest known evidence of hominins outside Africa, surpassing Dmanisi hominins found in Georgia by 300,000 years, although whether these hominins were an early species in the genus Homo or another hominin species is unknown.
Researchers say they have identified a new species of ancient hominin, Homo juluensis, that could help solve another big mystery of human evolution. Their proposal is sparking debate in the ...
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 human fossils found in the layers of sediment were originally difficult to date. Between Laotian laws protecting the remains and contaminating charcoal that had washed into the cave, several ...
