This course will investigate the variation that exists within our own species, both between and within populations. It will focus on the evolutionary and genetic basis of human variation, as well as its diversity, adaptive significance, and distribution. Topics covered will include: body shape and physiology, blood groups, susceptibility to disease, and skin color. It will survey the historical attempts to classify humans into different races, assess definitions of race as solely a cultural construct, and attempts to link race with intelligence and performance. Spring semester.
