I wasn't familiar with the term hominin and though it might be a misspelling of hominid, but that's not the case: https://australian.museum/learn/science/human-evolution/homi...

Hominid: the group consisting of all modern and extinct Great Apes (that is, modern humans, chimpanzees, gorillas and orangutans plus all their immediate ancestors).

Hominin: the group consisting of modern humans, extinct human species and all our immediate ancestors (including members of the genera Homo, Australopithecus, Paranthropus and Ardipithecus).
