3 Australopithecus Afarensis “Lucy” 2.7 – 4 Million years ago.Earliest known member of the Hominid family.Overall body size, brain size and skull shape closely resemble that of a chimpanzee.Thought to have lived along the northern Rift valley of east Africa.
4 Australopithecus Robustus 1 – 2.2 Million years ago.Believed to be small brained compared to humans.Huge teeth, Skulls, and Jaws were thought to be used to eat and chew through tough plants.
5 Homo Habilis 1.6 – 2.2 Million years ago. Earliest known species of the genus Homo “Human Species”30% larger brain then that of an Australopithecus Afarensis.Male Skull significantly larger than the female.
6 Homo Erectus 0.4 – 2 Million years ago. Much larger brain. Almost 50% bigger than Homo Habilis.Body is remarkably modern looking and the first species to stand over 6 feet tall.First species to create and use stone tools to complete tasks.Possibly used “Baby Talk” to communicate.
7 Homo Sapiens 200,000 – 400,000 years ago. Believed to be the earliest form of our own species.Wooden tools and weapons are evidence that they possibly lived a hunting lifestyle.
8 Neanderthalensis 30,000 – 200,000 years ago. Believed to have experienced thoughts and feelings a lot like us due to their brain growing to a little larger than ours is now.Scientists still debate whether they are a closely related sub-species of modern humans or represent a collateral line of late Homo erectus.Looked, moved, and behaved very similar to us now.
9 Archaic Homo Sapiens Present – 30,000 years ago. Humans as we know them.Brain size a little smaller than that of the Neanderthals.Due to natural selection and chance mutation the brain developed to link the left and right side giving us the ability to multi-taskSmaller teeth, and Jaw compared to earlier species.The Smartest of the species thus far.
