The chimpanzee–human last common ancestor (CHLCA) is the last common ancestor shared by the extant Homo (human) and Pan (chimpanzee and bonobo) genera of Hominini.Estimates of the divergence date vary widely from thirteen to five million years ago.
Dawkins lists "concestors" of the human lineage in order of increasing age, including hominin (human–chimpanzee), hominine (human–gorilla), hominid (human–orangutan), hominoid (human–gibbon), and so on in 40 stages in total, down to the last universal common ancestor (human–bacteria).
Before the discovery of Ardipithecus and other pre-Australopithecus hominins, it was assumed that the chimpanzee–human last common ancestor and preceding apes appeared much like modern-day chimpanzees, orangutans and gorillas, which would have meant these three changed very little over millions of years.
Species close to the last common ancestor of gorillas, chimpanzees and humans may be represented by Nakalipithecus fossils found in Kenya and Ouranopithecus fossils found in Greece. Molecular evidence suggests that between 8 and 4 million years ago, first the gorillas (genus Gorilla ), and then the chimpanzees (genus Pan ) split off from the ...
The human and chimpanzee evolutionary lineages split about 6.9 million to 9 million years ago, according to research published in June. ... adaptations were present in the last common ancestor ...
Traditionally, chimpanzees, gorillas and orangutans were grouped together, excluding humans, as pongids.Since Gray's classifications, evidence accumulating from genetic phylogeny confirmed that humans, chimpanzees, and gorillas are more closely related to each other than to the orangutan. [3]

Panina [2] is a subtribe of tribe Hominini; it comprises all descendants of the human-chimpanzee last common ancestor (LCA) that are not of the branch of human lineage—that is, all those ancestors of the type genus Pan, (chimpanzees and bonobos).
