The term Hominin is usually used in reference to Homo Sapiens and extinct bipedal ancestors. In comparison, Hominid is used for all modern and extinct great apes, including humans, chimpanzees, gorillas, and orangutans. However, this classification varies based on different perspectives in classification and will doubtlessly be changed.
