@oristarA,
I'm not sure. To me, the "great apes" just means the biggest ones, which would be such species as gorilla, orang-utan, chimpanzee, bonobo and maybe one or two more.
Not monkeys.
(EDIT) The Wikipedia entry includes the following:
The Hominidae (play /hɒˈmɪnɨdiː/; also known as great apes[notes 1]), form a taxonomic family of primates, including four extant genera: chimpanzees and bonobos (Pan),[notes 2] gorillas (Gorilla), humans (Homo), and orangutans (Pongo).[1]
The term "hominid" is also used in the more restricted sense as hominins or "humans and relatives of humans closer than chimpanzees".[2] In this usage, all hominid species other than Homo sapiens are extinct.
