They have been denounced and debunked. Since race is a construct there are not racial genetic differences.
They have been denounced. They have never been debunked. Where is there evidence of intrinsic racial equality? Race is an issue where the more one ignores science the more enlightened one is said to be.

"The Inequality Taboo," by Charles Murray,
Commentary, September 2005
The Harvard geneticist Richard Lewontin originated the idea of race as a social construct in 1972, arguing that the genetic differences across races were so trivial that no scientist working exclusively with genetic data would sort people into blacks, whites, or Asians. In his words, "racial classification is now seen to be of virtually no genetic or taxonomic significance."
Lewontin's position, which quickly became a tenet of political correctness, carried with it a potential means of being falsified. If he was correct, then a statistical analysis of genetic markers would not produce clusters corresponding to common racial labels. In the last few years, that test has become feasible, and now we know that Lewontin was wrong.
Several analyses have confirmed the genetic reality of group identities going under the label of race or ethnicity. In the most recent, published this year, all but five of the 3,636 subjects fell into the cluster of genetic markers corresponding to their self identified ethnic group. When a statistical procedure, blind to physical characteristics and working exclusively with genetic information, classifies 99.9 percent of the individuals in a large sample in the same way they classify themselves, it is hard to argue that race is imaginary.

This is a good experiment because it can be repeated again and again. Putting this in my own words I will say that a person's race can usually be determined by appearance and always by DNA analysis.
Now that there is scientific proof that race is an important biological category It becomes relevant to see how the races differ in genetic inclinations toward high intelligence and inclinations toward crime. I an confident that the genetic evidence will confirm what has always been known about non cosmetic racial differences.
