Return to History 8 Human Origins Vocabulary
Australopithecines were the earliest hominids which lived 5-6 million years ago, and became extinct at around 1 million BC. The fossils of some of the first bipedal organisms reveal a lot of changes that occurred in the characteristics of their ancestors. As we move backward in time, it becomes harder and harder to distinguish the organisms that are human and not human from each other.
