Examples of Families in Primates Order

Australopithecus is a genus comprised of small-bodied and small-brained early hominin species (human relatives) that were capable of upright walking. 

Australopithecus Classification

The genus Homo has never been clearly defined, but includes modern day humans and other extinct species closely related to humans.

Homo- Classification

Sahelanthropus tchadensis is an early hominin species that lived around 6-7mya in Chad. Sahelanthropus tchandensis brain size is estimated to be about 360cc, had larger canines than the genus Homo, and possibly was bipedal.
