AFARENSIS

Lived in Eastern Africa, lived for more than 900,000 years. Longer than any other species.They grew rapidly, after birth they reached adulthood earlier than any modern human. Brain size is less than 500 cubic centimeters.

AFRICANUS

Lived in Southern Africa. Africanus had a smaller cranium size. They think it walked bipedally but the shoulders and hand bones indicate it was a climbing species also.

HABILIS

Lived in Eastern and southern Africa. One of the earliest members of HOMO, has a slightly larger braincase than Africanus. This species was the first thought to represent the stone-tool maker.

ROBUSTUS

Lived in Southern Africa. They had huge, broad cheek teeth, that focused their chewing to the back of the jaw. The big jaw and strong teeth gave them the ability to grind down tough foods. The name refers to face and tooth size not body size.

BOSIEI

Lived in Eastern Africa. Had a specialized skull with adaptions for heavy chewing, a wide and dish-shaped face to help support massive cheek teeth 4 times the size of modern human's. This species had larger teeth than Robustus. A brain size of about 100 cubic centimeters.

ERECTUS

maryah_idrogo — 2014-06-02 04:23:25 UTC

Lived in Northern, Eastern, Southern Africa. Western, East Asia. They think they might have had the ability to walk and maybe fun long distance. They were considered the first species to expand away from Africa. They were also believed as the longest lived early human species.

HOMO SAPIENS

Evolved in Africa, now worldwide. They gathered and hunted food and gained behaviors that helped them through the challenges to survive in unstable environments. Our jaws are less heavy with smaller teeth.
