The word “ape” isn’t a name of any species, BilliardsBall.
The word “ape” is a taxon classification of some shared physical and genetic traits of groups of primates (the taxon order, Primates).
Primates (order) is grouped together with other mammals in the class Mammalia.
Mammals, primates, apes, monkeys, fishes, sharks, birds, amphibians, frogs, dinosaurs, vertebrates, animals, plants, trees, bacteria, etc. None of these words that we use everyday to describe them, are names or labels of “species”.
Humans, as in the Homo sapiens (species) or Homo sapiens sapiens (subspecies) are the only species that are extant today in the genus Homo, which is a Latin word for “human”. Other human species in the Homo genus are extinct, eg Homo erectus, Homo heidelbergensis, Neanderthals, etc.
Homo isn’t a name of species, just as apes are not of species.
Humans are species of the Homo, but they are also species of other classification names:
- Homo (genus)
- Homonini (tribe), which includes the genera Homo and Australopithecus
- Hominidae (family), “great apes”
- Hominoidea (superfamily) “apes”
- Catarrhini (parvorder) “Old World monkeys”
- Simiiformes (infraorder) “monkeys”
- Haplorhini (suborder)
- Primates (order)
- Mammalia (class)
- Animalia (kingdom)
Humans are apes and primates, as well as they are mammals and animals. But words like apes and primates, in biology, don’t referred to as species.
We often used the word “fish”, eg on trout, barramundi, sardine, tiger shark, swordfish, etc, and yet “fish” isn’t a species. None of the fishes I had listed are of the same species; they don’t even belong to the same genus and same family.
We do the same thing with birds, but “birds” (class Aves) isn’t name of the species, nor are peregrine falcons are of the same species as that of doves or of pelicans.
And speaking of falcons, falcons isn’t the name of species, but that of the genus Falco and the family Falconidae. There are many different species and subspecies of falcons, so the peregrine falcons (Falco peregrinus) are of different species to the gyrfalcons (Falco rusticolus).
