Human Evolution Timeline

chimpanzee sized brain, walked upright on two legs, and had smaller canines like other early humans.

Sahelanthropus Tchadensis video

Species which "Lucy" belonged to. Has apelike proportions of the face, and strong arms with curved fingers for climbing. But, had small canine teeth and body that stood and walked upright on arched feet. Was able to survive dramatic climate fluctuations.
Australopithecus Afarensis

Had a bony ridge on the midline on the top of the skull. This crest anchored large chewing muscles from the top and side of the braincase to the lower jaw. Lived among Homo Erectus.
Paranthropus Boisei

We are the sole surviving species of our family species.
Homo Sapiens

Two femur bones show it walked upright, but other parts showed ape like features. Had long curved finger bones and ape like teeth.
Orrorin Tuugenensis

First early human species to be discovered on the continent of Africa. Members of this species was mostly vegetarian, and had diets much like the modern chimpanzee. Due to wear on the molars, we know that they ate tough foods.
Australopithecus Africanus

Evidence that the first early humans to make hearths, to eat significant meat and bone marrow, and take care of the old and weak. Longest lived species in the human evolution timeline.
Homo Erectus

Teeth showed primitive features. Evidence that it lived in more closed, wooden areas helps demonstrate that upright walking did not evolve in an open Savanna environment
Ardipithecus Kadabba

The bony ridge on the top of the skull in this species indicates huge chewing muscles, with a strong emphasis on the muscles that connect toward the back of the crest and created strong chewing forces on the front teeth.
Paranthropus Aethiopicus

Very similar to Homo Habilis, but it has larger braincase, longer face, and larger molar and premolar teeth.
Homo Rudolfensis
