Anthropology is a cross cultural study of humankind.
It's purpose is to understand who we are as a species, where we came from, and how different cultures within the human species have changed and continue to change. There are four major sub-fields within Anthropology, each studying the human species from a different aspect. By compiling the knowledge from all of these sub-fields, one can get a broad understanding of human culture. Physical Anthropologists Also called Biological Anthropologists, these people study the evolution of humans, our relationship with our environment, and our closest living relatives, other primates. They study the physical reasons for why humans have developed into the creatures you see before you today.
