Let's be accurate about that quote, though - that Vox article itself says that a lot of what goes into IQ is heritable, and comes through DNA. "No genes for IQ" is better interpreted as a statement that it's not just a small handful of genes that determine IQ (or any behavioral trait), but very, very many (plus nurture, but that goes without saying). It cites http://europepmc.org/articles/pmc4635473 http://europepmc.org/articles/pmc4635473, which mentions: The SNP rs9320913 is estimated to account for only 0.02% of the overall variability in educational attainment, but biometrical studies show that the total percentage of variability owed to genetic differences is three orders of magnitude larger (Heath et al., 1985; Rietveld et al., 2013). Since the SNPs with the largest effects are the easiest to find, these results suggest that educational attainment is a phenotype affected by thousands of undiscovered genetic variants, each responsible for a minuscule fraction of individual differences. ...which is not to say that Murray's claims that intelligence and race correlate strongly have merit, since as the article you posted points out, his argument has some severe deficiencies. Specifically (and this is coming from me, not the article), when a measured trait (say IQ) is a function of a large number of genes, then unless that trait has highly variable selective importance depending on habitat, we would not expect it to diverge significantly between races. Traits that do diverge significantly tend to be either subject to different selection pressures between environments, or involve a small number of genes (with a small number of genes, it's easy for random noise to freeze unusual variants into segregated populations, but as the count goes up the law of large numbers kicks in and we see similar bell curves in all populations). This is almost trivial to prove.
