Interviewee: Kenneth Kidd. Geneticist Kenneth Kidd speaks about the significance of genetic variation in humans. (DNAi Location: Applications > Human origins > Variation > Interviews > Genetic variation in humans)

It's very clear to anybody, who, in a cosmopolitan area looks at other people around them, that different people whose ancestry is primarily from different parts of the world tend to look different. The genetic variation is not distributed uniformly. Every independently conceived person is biologically and genetically different. But most of that difference exists between two individuals from almost any place in the world, and very small proportion of that variation is distributed unequally around the world. And that's a difference that can be medically very significant in terms of the rare variants causing diseases, may be different in different parts of the world, but in terms of morality and social factors and worth of an individual, it makes absolutely no difference.
