Document Summary
Allele that is beneficial stays while others die out. Key point: not about what happened, but who feels it more. The small population will feel genetic drift more. Coin toss, you"re not surprised when flipping four times gets all head. Find mate within (nation, ethnic group, region people, family) Mutation: only true way to have new material in genetic code. A category has a range of variation as a normal component. More categories the better (minimal variation within a category) Geocentric: everything revolves around the earth and the earth and humans are perfect. Linnaeus classified four categories with behavioral and intellectual qualities. Blumenbach (1752-1849) classified five races based on more than skin color. Since 1600s, race has been used to refer to culturally defined groups. Race is used as a biological term, but has enormous social significance. Racial traits are not the only phenotypic expressions that contribute to social identity: sex and age are also critically important.
