alt Hacker NewsIt's unfortunate that the URL happens to be buzzfeed, but there was an open letter to Reich by other academics about his terminology in the book you're quoting [0]. The short of it is that social categorizations we believe in like race intersect with genetics in a very complicated way. Reich is a world-class expert in genetics. He simply commits the same error as many other other experts in discounting the complexity of subjects he's adjacent to, but not directly an expert in.
I get that this is a high standard to hold him to (and I sure as heck don't meet it myself), but he should do better given his visibility in public discourse.

Fortunately, there are many wise laymen such as yourself in the internet to correct him.

Please explain the complications. Use scientific terms only.

Why? He presented real verified science. Anyone who is offended or does not like it ... well, too bad... the world does not care. Facts are facts. He does not owe you or anyone else comfort. He presents cold hard truth, and sometimes truth hurts. Tough.
The crux of that letter is the "need to recognize that meaningful patterns of genetic and biological variation exist in our species that are not racial." This is true. However, this does not mean that there aren't also meaningful patterns of genetic and biological variation that do stratify according to ancestry (not race!). The letter tries to handwave this away, claiming that "[f]or several decades billions of dollars have been spent trying to find such differences. The result has been a preponderance of negative findings despite intrepid efforts to collect DNA data on millions of individuals in the hope of finding even the tiniest signals of difference." This is simply not true, as studies like the subject of this discussion demonstrate.
The letter also states that "[t]he public should not cede the power to define race to scientists who themselves are not trained to understand the social contexts that shape the formation of this fraught category." Also true! This is exactly why Reich explicitly avoids discussing "races" but rather populations and ancestries, which are rigorously defined strictly in terms of genetics. With respect to population structures and ancestry, Reich is indeed an expert.
I'll add that very few of the signatories of that letter have any experience, let alone expertise in genetics. Here are the first few:
Out of the 67 signatories, I counted approximately 5 who might have sufficient genetics expertise to offer a meaningful scientific counterpoint to Reich's work (this is being charitable, as I included titles like "Professor of Biological Sciences," which is no guarantee.) The rest were in fields like anthropology, sociology, law, and history.
