Introduction and Early Evolution

Pan troglodytes, better known as chimpanzees, are a species of great ape widely regarded as the closest living relatives to bonobos (Pan paniscus) and one of the closest living relatives to humans (Homo sapiens; Fig. 1).[1][2]

The evolution of chimpanzees is thought to have begun, like that of many other primates, with the divergence of platyrrhines (also known as New World monkeys) and catarrhines (a group containing Old World monkeys and apes) 25-40 million years ago [3] This was followed by a divergence in the catarrhines, forming the Hominoidea (ape) and Cercopithecoidea (Old World monkey) groups 23 million years ago. [4] It is estimated that the genera Homo and Pan diverged 5-6 million years ago, followed by a split in the genus Pan roughly 2.4 million years ago, eventually culminating into the chimpanzees and bonobos present today (Fig. 2).
