No.

>However, unlike the term “race,” it focuses on understanding how a person’s history unfolded, not how they fit into one category and not another. In a clinical setting, for instance, scientists would say that diseases such as sickle-cell anemia and cystic fibrosis are common in those of “sub-Saharan African” or “Northern European” descent, respectively, rather than in those who are “black” or “white”. (quoting http://sitn.hms.harvard.edu/flash/2017/science-genetics-resh...) //

That's just linguistic spin.

>Ultimately, while there certainly are some biological differences between different populations, these differences are few and superficial. //

So Cystic Fibrosis and Sickle-Cell disease are superficial?

>For instance, alt-right proponents have stated, correctly, that many people with European and Asian descent have inherited 1-4% of their DNA from Neanderthals ancestors, and those of African descent do not have Neanderthal heritage. //

Hang on, they said earlier that we share 99% of our DNA with all other humans -- that being proof there are no races (according to the piece) -- but if we share 99%, how can Europeans/Asians have up to 4% Neanderthal that Africans don't have.

Now add in things like "we share 99% of our DNA with chimps" (https://www.scientificamerican.com/article/tiny-genetic-diff...) and we have a simplistic analysis suggesting we're much farther from other humans than we are from chimpanzees. I don't think that's what the authors wanted their piece to be suggesting.

The piece is unconvincing, badly written IMO, and lacks rigour.

Something they might have addressed is how the likes of 23andMe can give you a ethno-geographic background profile if it's impossible to tell from someone's genes what "race" they are.
