Read the links. Because those
aren't providing evidence for the claim. They're just repeatedly asserting what I've already told you is faulty reasoning:
we don't have a precise genetic definition of "race" today, therefore it doesn't exist.That's wrong. Regarding the specific papers:
The first explicitly admits that race exists in the opening sentence (oops), then proceeds to say "the two most commonly used biological concepts of race" don't work in humans, therefore race doesn't exist ("There are no objective criteria for choosing one adaptive trait over another to define race. As a consequence, adaptive traits do not define races in humans.")
This is exactly the fallacious thinking I'm calling out. Great example.
The second is not a paper at all, but still admits that there's at least some biological basis for race, even though it's not precise. That's fine -- I'm not claiming it is precise:
> Research indicates that the concept of “five races” does, to an extent, describe the way human populations are distributed among the continents—but the lines between races are much more blurred than ancestry testing companies would have us believe
The third is saying that a single, specific measurement of genetic diversity fails to define race. Again, that's fine. Saying "test X doesn't define race" != "race does not exist":
> These limitations on FST are demonstrated algebraically and in the context of analyzing dinucleotide repeat allele frequencies for a set of eight loci genotyped in eight human groups and in chimpanzees. In our analyses, estimates of FST fail to identify important variation.
Overall, these illustrate exactly what I've said: race is clearly real and we know it when we see it, but it's not precise, and we don't have a biological test that defines it. Those who extend this to "race is a sociopolitical construct" are engaged in a through-the-looking-glass form of motivated reasoning. And it's a very convenient form of reasoning, because if you make it "wrong" to say that race exists, you prevent anyone from doing the research that might produce such a test.
