Hominids were human-like creatures that walked upright.
Olduvai Gorge: The location in East Africa where the oldest hominid at the time (1959) was discovered at 1.8 million years old.
Australopithecus: A type of hominid known to be the common ancestor for many types of early human life.
The existence of the Australopithecus proved that hominids walked on two legs before creating tools.
The hominid Homo Habilis came after the Australopithecus and may have used stone tools.
The hominid Homo Erectus had the arm and leg proportions that modern humans have.
Homo Sapiens were more complex hominids.
Homo sapiens sapiens: Hominids that have similar anatomy to modern humans and existed in Africa 150,000-200,000 years ago.
“out-of-Africa” theory: The theory that Homo sapiens sapiens replaced earlier hominids in Europe and Asia after spreading out to other parts of the world.
Neanderthals died out by 30,000 B.C. which may have been from conflicts with Homo sapiens sapiens.
