Richard Lewontin - Work On Human Genetic Diversity

Work On Human Genetic Diversity

In a landmark paper, in 1972 Lewontin identified that most of the variation (80-85%) within human populations is found within local geographic groups and differences attributable to traditional "race" groups are a minor part of human genetic variability (1-15%). He argued that the probability of racial misclassification of an individual based on variation in a single genetic locus is approximately 30% and the misclassification probability becomes close to zero if enough loci are studied. In a 2003 paper, A.W.F. Edwards criticized Lewontin's conclusion that race is an invalid taxonomic construct, terming it Lewontin's Fallacy.

Famous quotes containing the words work, human, genetic and/or diversity:

    Art should exhilarate, and throw down the walls of circumstance on every side, awakening in the beholder the same sense of universal relation and power which the work evinced in the artist, and its highest effect is to make new artists.
    Ralph Waldo Emerson (1803–1882)

    By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.
    Owen Barfield (b. 1898)

    Man is not merely the sum of his masks. Behind the shifting face of personality is a hard nugget of self, a genetic gift.... The self is malleable but elastic, snapping back to its original shape like a rubber band. Mental illness is no myth, as some have claimed. It is a disturbance in our sense of possession of a stable inner self that survives its personae.
    Camille Paglia (b. 1947)

    ... city areas with flourishing diversity sprout strange and unpredictable uses and peculiar scenes. But this is not a drawback of diversity. This is the point ... of it.
    Jane Jacobs (b. 1916)
