I’d hazard a guess it comes down to vitamin D deficiency. Without vitamin D supplementation, which few people do seriously, a society which revolves around staying indoors most of the time would be most problematic for people whose skin is evolved for a significantly higher degree of sunlight, as opposed to white people, whose skin evolved for relatively little and to maximize vitamin D production on what little they do get.
Along similar lines, I’ve wondered if everyone in the U.S. going on a paleo diet would significantly lower the racial achievement gap. It would be ironic in the extreme if fear at looking into biological causes of group differences prevented us from finding easy-to-implement solutions to the achievement gap.
