I’m afraid you may be a bit confused on this. What are the odds that out of all ethnicities on the planet, only Ashkenazi Jews where the ones to develop a different IQ than the surrounding peoples? And only in the past thousand years or so. What about all those groups that have been isolated or differentiated in very different natural and even social environments for tens of thousands of years?
Unless you are using “the racial gap” to refer to the specific measured IQ differences between people of African, European and East Asian descent, which may indeed be caused by the envrionment, rather than the possibility of differences between human “races” in general. But even in that case the existence of ethnic genetic IQ differences should increase the probability of a genetic explanation somewhat.
