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:
“Whoever is not in the possession of leisure can hardly be said to possess independence. They talk of the dignity of work. Bosh. True work is the necessity of poor humanity’s earthly condition. The dignity is in leisure. Besides, 99 hundredths of all the work done in the world is either foolish and unnecessary, or harmful and wicked.”
—Herman Melville (1819–1891)
“Feeling without judgement is a washy draught indeed; but judgement untempered by feeling is too bitter and husky a morsel for human deglutition.”
—Charlotte Brontë (1816–55)
“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)
“We call the intention good which is right in itself, but the action is good, not because it contains within it some good, but because it issues from a good intention. The same act may be done by the same man at different times. According to the diversity of his intention, however, this act may be at one time good, at another bad.”
—Peter Abelard (1079–1142)
