Answer 1

The chimpanzee–human last common ancestor, or CHLCA, is the last common ancestor shared by the extant Homo (human) and Pan (chimpanzee) genera of Hominini. Due to complex hybrid speciation, it is not possible to give a precise estimate on the age of this ancestral individual.[citation needed] While "original divergence" between populations may have occurred as early as 13 million years ago (Miocene), hybridization may have been ongoing until as recently as 4 million years ago (Pliocene).

Speciation from Pan to Homo appears to have been a long, drawn-out process. After the original divergences, there were, according to Patterson (2006), periods of hybridization between population groups and a process of alternating divergence and hybridization that lasted several million years. Some time during the late Miocene or early Pliocene, the earliest members of the human clade completed a final separation from the lineage of Pan — with date estimates ranging from 13 million to as recent as 4 million years ago.
