McGraw-Hill These PowerPoint slides have been designed for use by students and instructors using the Anthropology: The Exploration of Human Diversity textbook by Conrad Kottak. These files contain short outlines of the content of the chapters, as well as selected photographs, maps, and tables. Students may find these outlines useful as a study guide or a tool for review. Instructors may find these files useful as a basis for building their own lecture slides or as handouts. Both audiences will notice that many of the slides contain more text than one would use in a typical oral presentation, but it was felt that it would be better to err on the side of a more complete outline in order to accomplish the goals above. Both audiences should feel free to edit, delete, rearrange, and rework these files to build the best personalized outline, review, lecture, or handout for their needs. Using These Slides

It shows how the biological and social categories of race are largely unrelated, and demonstrates this by discussing the construction of race in Brazil, Japan, and the United States. Human Diversity and Race

McGraw-Hill Race: Discredited in Biology ⧫ In biological terms, a race is a geographically isolated subdivision of a species that can reproduce with individuals from other subspecies of the same species, but does not because of its geographic isolation. ⧫ Human populations vary biologically, but there are no sharp breaks between populations. ⧫ Human biological variation is distributed gradually between populations along clines. ⧫ Ethnicity and race are not synonymous, although American culture does not discriminate between the two terms.
- 7. © 2002 by The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill Races Are Not Biologically Distinct ⧫ Race is supposed to describe genetic variation but racial categories (particularly early on) are based on phenotypes. ⧫ Phenotypes are the product of genetic, developmental, and environmental factors. ⧫ There is no clear logical hierarchy to phenotypic traits, thus it is difficult to demonstrate which should be a definitive racial feature. ⧫ The so-called three great races (white, black, and yellow) are more a reflection of European colonialist politics than an accurate representation of human biological diversity. ⧫ Even skin color-based race models that include more than three categories do not accurately represent the wide range of skin color diversity among human populations.

McGraw-Hill Fundamental Problems with Race ⧫ Populations grouped into one race based upon phenotypic similarity may be genetically distinct; such similarities may be the result of parallel evolution or other factors. ⧫ Genetic traits occur together due to the selective forces of the environments in which they evolved, and therefore do not constitute an internally coherent “type.” ⧫ “Race,” as it is used in everyday discourse, refers to a social category, rather than a biological category.

McGraw-Hill Explaining Skin Color ⧫ Natural selection “is the process by which nature selects the forms most fit to survive and reproduce in a given environment.” ⧫ Variation in skin color is determined by the amount of melanin in the skin cells, which is genetically determined. ⧫ Prior to the sixteenth century, darker skinned populations were closest to the equator, while lighter skinned populations were closer to the poles.

McGraw-Hill Explaining Skin Color ⧫ Light skin in the tropics is selected against because it burns more easily, thus subjecting light-skinned individuals to a greater likelihood of infection and disease. ⧫ Sunburn impairs the body's ability to withstand heat by reducing the skin’s ability to sweat. ⧫ Light skin is more susceptible to skin cancer. ⧫ The effect of sunlight on vitamin D formation indicates how dark skin might have been selected for in tropical environments (protection against hypervitaminosis D), and against in lower-sunlight environments (protection against rickets). It further indicates how light skin might have been selected for in low-sunlight environments, and against in the tropics.

McGraw-Hill Hypodescent: Race in the US ⧫ In the United States, race is most commonly ascribed to people without reference to genotype. ⧫ In extreme cases, offspring of “genetically mixed” unions are ascribed entirely to the lower status race of one parent, an example of the process called hypodescent. ⧫ The arbitrary lumping of bisexuals with homosexuals and the controversy surrounding the casting of Eurasian roles in the play, Miss Saigon, are suggested as examples of hypodescent. ⧫ In the US, there is a growing number of interracial, biracial, or multiracial individuals who do not identify themselves with one “racial” identity.

McGraw-Hill Not Us: Race in Japan ⧫ Despite the presence of a substantial (10%), various minority population, the dominant racial ideology of Japan describes the country as racially and ethnically homogeneous. ⧫ Dominant Japanese use a clear “us-not us” dichotomy as the basis for their construction of race. ⧫ While dominant Japanese perceive their construction of race to be based upon biology, the burakumin construct provides evidence to the contrary. ⧫ Burakumin are descendants of a low-status social class. ⧫ Despite the fact that burakumin are genetically indistinguishable from the dominant population, they are treated as a different race. ⧫ The mixed Japanese-Koreans are treated as wholly foreign, despite otherwise complete cultural and linguistic assimilation.

McGraw-Hill Race in Brazil ⧫ While it has some historical and social similarities with the United States, race in Brazil is very different from race in the United States and Japan. ⧫ The Brazilian construction of race is attuned to relatively slight phenotypic differences. ⧫ More than 500 distinct racial labels have been reported. ⧫ Brazilian “race” is far more flexible than the two other examples cited, in that an individuals racial classification may change due to achieved status, developmental biological changes, and other irregular factors. ⧫ The multiplicity and overlap of Brazilian race labels allows one individual to “be” more than one race. ⧫ The complex flexibility of Brazilian race categories has made racial discrimination less likely to occur on the same scale as in the United States and Japan.
