Biological Differences that Exist Between Individuals in a Population E

biologic Differences that Exist Between Individuals in a cosmos Physical anthropologists view homos as biological organisms. Coupled with genetics and biochemistry, scientists can form a more complete picture of benignant anatomy, both past and present. Physical anthropology looks at human variation and evolution. vicissitude looks at the biological differences that exist between individuals within a world and at individuals between populations (e.g., body shape, size, and physiological responses). These differences in human biological science are measured using a technique called anthropometry 1. In rewrite 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 boast occurred all over the years leading up to modern day Homo sapiens. In ord er to determine the changes that have taken place in human anatomy we rely on paleoanthropology, the area of human fossil remains, and primatology, and the study of other primates 1. Paleoanthropology helps us determine who our ancestors were, and when, how and why they evolved. Primatology allows us to see the similarities and differences between other primates and ourselves and allows us to trace these evolutionary relationships. For example, such a study has determined that humans share or so 98.6% of their DNA (their genetic code) with gorillas, 98.8% with chimpanzees and 97.6% with orangutans 2.Approaching human variation from the perspective of the anthropologist leaves a vast field of study before the world of medicine. One of the near fascinating examples of human variation is the found in albinism.The word albinism refers to a group of genetically inherited conditions. People with albinism have little or no pigment in the eyes, skin, and hair (or in some cases in the eye s alone). They have inherited from their parents an altered copy of genes that does not turn over correctly. The altered gene does not allow the body to make the normal amounts of a pigment called melanin.Approximately one in 17,000 people have one of the types of albinism. About 18,000 people in the United States are impact 3. Albinism affects people from all races.
