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.
Chimpanzees are considered endangered because of habitat destruction, poaching, and infectious diseases. The total population in the wild is estimated at about 170,000 to 300,000, according to the ...
