There very obviously is a good reason why European and Anglo-Saxon populations dominate cutting edge science, even without going into "inherit" factors: The GDP/capita and incomes of these countries/ethnicities were and are far higher than those of Africans or Asians (especially 40 years ago when current laureates where educated), so more people can go into science careers that need 18+ years of schooling and have uncertain payoffs compared to industry careers. These countries also have far better funded universities and science institutes to make science without immediate payoff possible.
