Diamond asserts in his book Guns, Germs and Steel that white have been more dominate over the natives because of environmental influences. He denies any racial superiority of whites over other races, instead focuses on the non-racial impacts. For example, the importance of farming and the development of farming in specific regions. The climates in certain areas were more condusive to the growth of important crops - leaving areas that were not prime for farming less developmed (like New Guinea). The dominance of white peoples developed more by happenstance (luck of climate and location) than actual differences (intelligence, strength, etc) between the people.
- Diamond rewords the question as “History followed different courses for different peoples because of differences among people environment not because of biological differences among peoples themselves.”
