Contents. Early studies on human diversity showed that most genetic diversity was found between individuals rather than between populations or continents (e.g., Boyd 1950; Lewontin 1972) and that variation in human diversity is best described by geographic clines (Livingstone 1962; Cavalli-Sforza et al. diversity is substantially lower than that of many other species, including our nearest evolutionary relative, the chimpanzee. 13 terms.

Genetic diversity is a function of a population's "age" (i.e., the amount of time during which mutations accumulate to generate diversity) and its size.
