Exam 3 Race Recap: racial categories are not real things, arbitrary, classification based on geography and skin color Is it real? A real aspect of social issues, affects people's lives, arbitrary but can matter, anthropology has played key role in scientific racism but now they say race is not real. Do humans vary biologically? Relatively homogenous compared to other species, they vary though Caveats: Ancestry, subjective indicators Genetic Traits: traits associated with race are continuous: height, weight, skin color, head shape, body proportions Discrete: Present or Absent- determined by a single trait Continuous: Polygenic- range, many factors go into it Genetics Phenotypic variation = genetic & environmental Environmental variables include nutrition, disease, pollutants, socio- economics, climate Polymorphism: two or more distinct phenotypes exist in a random-mating population (sexual dimorphism/ blood types ) 3 alleles for antigen and i is nothings, one inherited from each parent Adaptations to Disease Syphilis : more frequent in type A, B, AB- more frequent in america Plague: more frequent in Type O - rampant in europe and asia Malaria and Sickle Cell Anemia HOmozygous for Sickle Cell- have severe symptoms Heterozygous- usually asymptomatic or mild symptoms; carrier- resistance to malaria Homozygous- no anemia Geographical distribution of malaria aligns with distribution of Skin Pigmentation Polygenic, continuous trait Dependent of hemoglobin, keratin, melanin Melanin determines skin tone Adaptation of different light radiation Not enough melanin- higher rate of skin cancer Too much melanin- vitamin D deficiency Is the idea of race a useful categorization of human biological variation? Race conflates cultural and biological variation NO it is not Humans are more closely related to chimps than chimps are to orangutanes Geographical distribution of chimps is not very large but they vary a lot more Current Science indicates all humans share a recent common ancestry

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
