1. Human Evolution Graphic Timeline

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-task
Smaller teeth, and Jaw compared to earlier species.
The Smartest of the species thus far.
