Summary Introduction
To determine:
The four groups of species in the hominin family tree, and also to determine the species that is still alive.
Concept introduction:
Hominins refer to humans and their extinct ancestors. They differed from other primates in walking straight on two legs, a process called bipedalism. They had adaptation such as longer and stronger legs and shorter arms for bipedalism unlike other groups of primates.
