Introduction
A primate is essentially a mammal of order primates that contains simians and prosimians. Primates rose from the ancestors that survived in trees of tropical forest. It is important to note that many characteristics of the primates represent the adaptations to life in the tropical forest three dimensional environments. Most species of primate remain at least partially arboreal. For that reason, this paper centers on the characteristics, which define order of primates, specifically contrasting and comparing Homo Sapiens or humans and chimpanzees or Pan troglodytes. These characteristics include locomotion, brain size, tool used, as well as facial expressions and language.
