Human genetic diversity of South America reveals complex history of Amazonia. Humans have approximately 30,000 genes. 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. life chances. that "all men are created equal" that slavery was first challenged
