Cyclone Posted January 30, 2014 Share Posted January 30, 2014 If its in our genes, specifically those from Neanderthals that makes us addicted to smoking, then as sub Saharan populations are supposedly without those genes they should not have that addiction you would think. http://www.sciencedirect.com/science/article/pii/S0376871605004023 But they do. Presumably these genes have some beneficial effects as well, if they were only ever harmful they would have rapidly been bred out of the gene pool. (For reference, think about sickle cell anaemia and how it protects from Malaria). Link to comment Share on other sites More sharing options...
