Is there a biological basis for race (re: Nicholas Wade's article)
I think it's best if you check out Wikipedia article on Race. Race is not a taxonomic term. In a nutshell, you can't define it in a useful way that has anything to do with the usual associations of the word, or gives it a practical value in science.

The problem with arguing about the existence of races in humans is that this is an argument about a word without an agreed definition, so there's never a true or false. This author is merely making some controversial extrapolations from quite obvious biology: Of course human genomes change over time, and it is also possible to an (impressive) extent to trace genetic lineages geographically. Of course there are subgroups that share a small set of characteristics not found in the rest of the human population. Some of these subgroupings are for example medically relevant.

Essentially, "race" ends up a loosely defined term that has something to do with subgrouping a species based on whatever criteria chosen. The reason why it's not a useful word to argue about in humans is because whatever subgrouping you might make, and for whatever purpose you are subgrouping, there are better, more meaningful (and quite importantly, less controversial) terms to describe those subgroups.
