Physical anthropologists view humans as biological organisms. Coupled with genetics and biochemistry, scientists can form a more complete picture of human anatomy, both past and present. Physical anthropology looks at human variation and evolution. Variation looks at the biological differences that exist between individuals within a population and at individuals between populations (e.g., body shape, size, and physiological responses). These differences in human biology are measured using a technique called anthropometry 1. In order to explain this diversity, physical anthropologists look to environmental conditions (including culture) and genetics. Taking these factors into account, the anthropologist attempts to formulate an evolutionary explanation for the differences.
Human evolution looks at the bodily changes that have occurred over the years leading up to modern day Homo sapiens. In order to determine the changes that have taken place in human anatomy we rely on......
