Document Summary

Ethnicity: identification with, and feeling part of, an ethnic group and exclusion from certain other groups because of this affiliation. Ascribed status: social status that people have little or no choice about occupying. Achieved status: status that comes through talents, choices, actions and accomplishments. Convergent evolution: independent operation of similar selective forces; the process by which analogies are produced. Homologies: when multiple species retain similar traits that come from a common ancestor. Analogies: when multiple species develop the same trait even though they came from different ancestor. Sexual dimorphism: when the males and females of a species have different features, like overall size/height, teeth, size, organs, hormones, etc. besides the contrasts in breasts and genitals. Trends in primate evolution: grasping ability (arboreal: tree dwelling; opposable thumb), smell to sight, nose to hand, increased brain complexity, parental investment, sociality. Arboreal: resides mostly in trees, corresponds to brachiation and quadrupedalism. Terrestrial: resides mostly on the ground, corresponds to bipedalism.
