Quizplus · Accepted Answer

Sahelanthropus tchandensis is one of the earliest known species on the human lineage, dating to about 7 million years ago. Though it is not yet clear whether Sahelanthropus is a direct ancestor of humans, it is an early member of the hominid lineage and provides insights into the early evolution of bipedalism. The other options listed, Australopithecus afarensis, Paranthropus, and Orrorin tugenensis, are also early hominid species, but they are not as early as Sahelanthropus in the evolutionary lineage leading to modern humans.
