there's this one at least :
Racial groupings match genetic profiles, Stanford study finds

besides the differences the physical anthropologists have discovered are real. You may believe they're irrelevant because they haven't been genetically located yet but they're very useful on crimes scenes or historical sites where there are skeletons.
and speaking of crime DNA Genomics Print is a company that the police is increasingly using to identify suspects. Their genetic test identifies ancestry and in the case below they even identified the suspect's nordic aspect

so when someone looks at the right set of genes/markers the lineage - race/ethnic group - of a person can be identified.
isn't that the Lewontin fallacy, the "there is more genetic variation between individuals than between groups" ? It is usually followed by a claim that for example it is possible for an african to be more genetically similar to a european than the latter to another european. I've never read or heard anyone quantify this possibility. What are the chances, 1 in 10 or 1 in 1000000000000000 ?
But again if it can so much why is it never quantified ? Have you read AWF Edwards's paper on what he calls the Lewontin fallacy, which is the base on which Lehrman's assertion quoted above is built ?

those can be subjective and flawed too. Richard Lewontin and DNA Genomics Print both work with genes/DNA yet their conclusions on the existence of races are different. The marxist zoologist says the categories are meaningless because it leads to racial discrimination, the other uses genetic tests that discriminate between human groups to help the police solve crimes.
OK populations then. Cavalli-Sforza may be publicly politically correct because he insists that races don't exist but his research show that it is possible to distinguish groups of humans from other humans on a genetic basis.

Racial lineages can be visibly, physically and genetically distinguished.
One example of racial difference in ear wax and nitroglycerin tolerance :

There's even a heart pill for blacks only, BiDil.
What do race-based or population-based genetic differences mean if humans aren't supposed to be classifiable in biologico-geographical sub-groups ? The differences exist but the groups to which they are linked to don't ?
