Because no species other than Homo sapiens has survived from the human line of that branching, both … 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. Due to complex hybrid speciation, it is not currently possible to give a precise estimate on the age of this ancestral population. While … See more The taxon tribe Hominini was proposed to separate humans (genus Homo) from chimpanzees (Pan) and gorillas (genus Gorilla) on the notion that the least similar species should be separated from the other two. … See more No fossil has yet conclusively been identified as the CHLCA.
