... Those who do not understand the power of genes might argue that the medal podium for runners should reflect a rainbow of diversity, as no country or region should have a lock on desire or opportunity. But just the opposite has happened in track and field: running has become almost segregated by ancestry. The trends are eye opening: Among men, athletes of African ancestry hold every major running record, from the 100m to the marathon ... But still journalists, unschooled in genetics 101, who bow to political correctness, attempt to persuade us that environment and culture are what matters most at the elite levels of competitive sports ... The cultural arguments pale against the hard science ... Evolution has shaped significant physical and physiological differences ... We have no choice but to face this third rail of genetics and sports.
