What do you understand by hominins?</h3>
The term "hominin" refers to a group that includes all living humans, all extinct human species, and all of our direct predecessors (including members of the genera Homo, Australopithecus, Paranthropus, and Ardipithecus). Sahelanthropus, Orrorin, and Ardipithecus are the earliest hominins. Many characteristics that set humans apart from other primates were absent in the ancestors of the human lineage. Sahelanthropus tchadensis from the Chad and Orrorin tugenensis from Kenya are the oldest hominins that are currently known. The skull of Sahelanthropus, which dates to between 6 and 7 mya, is mostly complete, and there are also some additional fragmentary bones.
