Innate biological differences across cultures: 2 people living in different cultures have experiences within their own lifetimes that have an impact on their biology, acquired biological differences. Genetic variation across populations: considerably less in humans than in many other species because humans only emerged as a species recently. Ethnic tibetans have evolved genetic variants that allow them to thrive despite the low levels of oxygen.
