Who are our ancestors really? How does brain size affect intelligence? Why do we have two hands? Anthropology is a science with an age approaching a round date of 2500 years—it studies everything related to humans, from the structure of the cell to the mysteries of the soul and the arrangement of society as a whole. Why are you the way you are? And how does human physiology shape our social appearance? Brain size, eye structure, the length of arms and legs, and even the absence of a tail—these have determined the fate of all humanity. This book tells about a person from both physical and social perspectives.
