The chimpanzee and the bonobo are the only species in the genus Pan. Evidence from fossils and DNA sequencing shows that Pan is a sister taxon to the human lineage and is thus humans' closest living relative. The chimpanzee is covered in coarse black hair but has a bare face, fingers, toes, palms of the hands, and soles of the feet.
Experimentation on great apes—a smaller family within the ape superfamily—is currently banned in the European Union, the United Kingdom, and New Zealand (29 countries total). [1] These countries have ruled that chimpanzees, bonobos, gorillas and orangutans are so cognitively similar to humans that using them as test subjects is unethical.
A chimpanzee's testicles are unusually large for its body size, with a combined weight of about 4 oz (110 g) compared to a gorilla's 1 oz (28 g) or a human's 1.5 ounces (43 g). This relatively great size is generally attributed to sperm competition due to the polygynandrous nature of chimpanzee mating behaviour .

The World Wildlife Fund (WWF) estimates there are as many as 115,000 individuals alive, [1] but that the number is more likely between 47,000 and 78,000 [3] The central chimpanzee only has large, robust populations where large amounts of forest are left undisturbed; smaller, isolated populations also remain. According to the IUCN, decline in ...

Emperor tamarin, a New World monkey. Apes and monkeys spread from Africa into Europe and Asia starting in the Miocene. [56] Soon after, the lorises and tarsiers made the same journey.
