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.
The western chimpanzee or West African chimpanzee (Pan troglodytes verus) is a Critically Endangered subspecies of the common chimpanzee. It inhabits western Africa, specifically Côte d'Ivoire , Guinea , Liberia , Mali , Senegal , Ghana , Guinea-Bissau , but has been extirpated in three countries: Benin , Burkina Faso , and Togo .

The gorilla–human last common ancestor ( GHLCA, GLCA, or G/H LCA) is the last species that the tribes Hominini and Gorillini (i.e. the chimpanzee–human last common ancestor on one hand and gorillas on the other) share as a common ancestor. It is estimated to have lived 8 to 10 million years ago (T GHLCA) during the late Miocene. [1] [2] [3] [4]
The last universal common ancestor (LUCA) is the most recent common ancestor of all current life on Earth, estimated to have lived some 3.5 to 3.8 billion years ago (in the Paleoarchean ).
