Final answer:
Hominins do not include gorillas and chimpanzees; they are more narrowly defined to represent only modern humans, extinct human species, and all immediate human ancestors, which excludes gorillas and chimpanzees.
Step-by-step explanation:
The question posed is whether hominins include gorillas, chimpanzees, humans, and immediate human ancestors, where the answer is False. The term hominin is specifically used to refer to the group representing modern humans, extinct human species, and all of humanity's immediate ancestors, including the genera Homo, Australopithecus, Paranthropus, and Ardipithecus. In contrast, hominids refers to all modern and extinct great apes, which includes humans, gorillas, chimpanzees, orangutans, and their ancestors. Thus, while hominids do include gorillas, chimpanzees, humans, and their ancestors, hominins are more narrowly defined and do not include gorillas and chimpanzees.
