George Gaylord Simpson (1945) divided the order Primates into two suborders: the Prosimii (lemurs, lorises, galagos, and tarsiers) and the Chimpanzees are not only close to us biologically,they are also quite near in intelligence and live in highly complex social groups. For instance, same-sex fellatio — the reception of With living apes so variable in their sexual preferences, it’s tough to work out the sex habits of the ancestor common to humans and chimps.
