Document Summary
Cultural anthro must be based on cultural relativism. Includes enthnography (firsthand observations of a culture) & ethnolinguistics. Principals of darwinism: overproduction of offspring, variation within a species, so individuals with favourable characteristics are more likely to survive than others. Reproduction of the fittest, inheritance of desirable traits, creation of new species. Darwinian evidence: domestication/artificial selection of plants and animals; geographic distribution of life forms (isolation ex. A trait must be inherited to have importance in natural selection, cannot occur without variation, fitness is a relative measure determined by the environment and = differential reproductive success. Macro/micro evolution refer to amount of time involved. Directional: linear pattern of change to a physical trait over time (ex. increase in average size) Stabilizing: selection away from the extremes of a continuum (ex. not too big, not too small) Disruptive: selection towards extremes (ex. male and female)
