Humans are hominoids. Hominoidea is a taxonomic group. Phylogenetic systematics holds that taxonomic groups should be monophyletic — meaning that they include all the descendants of one ancestor, and don’t leave any descendants out. Humans are closely related to chimpanzees and bonobos, more distantly to gorillas, then orangutans, then gibbons. All these living creatures are crown hominoids. The Hominoidea includes all these, together with extinct animals like Australopithecus, Proconsul, Dryopithecus, and many others. Chimpanzees are apes. Gorillas are apes, as are bonobos, orangutans, and gibbons. We routinely differentiate the “great apes” from the “lesser apes”, where the latter are gibbons and siamangs. Humans are not apes. Humans are hominoids, and all hominoids are anthropoids. So are Old World monkeys like baboons and New World monkeys like marmosets. All of us anthropoids. But humans aren’t monkeys.
