What do you mean by race? Because race isn't genetically determined, its socially determined--two people of a very different "race," can actually be quite closely related genetically, its just that their appearances differ.
>does not give credibility to the side which continues to maintain that evolution has [by all significant measures] stopped at the neck.
Its not that evolution has or hasn't stopped at the neck, its that the IQ test as a single objective measure of intelligence, like measuring height, is incredibly flawed since it has changed dramatically in the decades when these studies have been conducted.
Whether or how someone is intelligent cannot be measured empirically by a single standard since purely intelligible things, like concepts, math, artistic ability, by nature cannot have an empirical appearance. But you know if someone is smart, and you know it because they tend to do things that are smart. But that's only helpful at the level of a single individual, its not something that can be measured population wide.

The most "post-modern" thing here is your comment, which you clearly wrote without having actually read the article thoroughly.
