Says the author of that article, who admits he is in the minority:
"... many evolutionary biologists state as if it were an unquestionable fact that humans are apes. I disagree."
Nomenclature is somewhat invented and imprecise. The author's assertion: ""Ape" is an English word. It is not a taxonomic term. English words do not need to be monophyletic." is factually correct, but also dismisses the fact that the way most scientists use the term in English
is monophyletic.
The author further states:
"If we must accept that humans are apes, then we must equally accept that chimpanzees are monkeys, and those awful parents at the zoo are right. I don't. I see value in precision about phylogeny, and for that purpose I have taxonomic terms. Humans are hominoids, and anthropoids, and haplorhines, and primates. And mammals."
He makes some good points and raises some thoughtful questions. But mainstream anthropology and primatology disagree with his conclusion. Ultimately language is about conveying meaning, and the meaning that mainstream science has agreed upon is that humans are apes.
