Document Summary
Biological variability of human: two categories for variation in human biology(cid:224) the innate and the acquired. Genetic variation across population: humans in different parts of the world were subject to different selection pressure over generations resulting in human genome diverging; there are innate biological differences. There is less genetic variability across the different races of humans that there is across different populations of chimps: more over, there is more genetic variation within africans then africans and ot others cultural background. In sum, humans compared with other species are less genetically distant from each other but different populations of humans do differ from each other in many of genes. Skin color is an example of the adaptive response to climatic differences among populations. But we can be sure that cultural experiences can shape how genes are expressed in body (korean american (cid:0) more similar to american then koreas even though the genes are the same)
