Good luck getting race - or nationality - out of that. btw: the article is I believe a bit off in some key respects, such as this: The key factor not clarified, and critical here, is between-population difference. Also: It's not true that the remaining variability in height is genetic, merely because diets have been reduced in influence. Other factors abound, that can vary or not vary between populations independently of diet. And it's not quite true, or informative anyway, that one has identified genetic contribution to "height" by eliminating the environmental variables that influence height. A genetic vulnerability or immunity to various childhood diseases endemic or absent from various places, for example, will affect height. Do people really want to say that these kinds of genetically mediated factors are "height" genetics? When they have these 108 polymorphisms that "explain" 3% of schizophrenia, say, what exactly have they found? A heightened vulnerability to fungal toxins in commercially processed food?
