Regardless of who wrote the history books, it is an undeniable fact that the Europeans arrived in large sailing vessels with a technology far advanced beyond the native residents of North America. It is an undeniable fact that while the population of Asia was responsible for many inventions, and developed a high culture with fine arts of all kinds, they did not expand to Europe or the Americas. The inhabitants of sub-Saharan Africa, despite having essentially the same brains as Europeans, did not develop the technology to travel to other continents.
The Middle East, northern Africa, and Europe did develop an advanced technology, written language, and did travel to every other continent on the planet.
In the book I cited, Diamond points out the following:
The Middle East and Europe had large draft animals: horses, oxen, cattle. They had other easily domesticated food animals such as sheep and goats. The east-west orientation of Eurasia provided a large expanse of land with a similar temperate climate, across which animals, plants, culture and technology could spread and flourish.
Africa has not a single domesticatable large mammal. With the exception of the llama, neither do the Americas. The llama, moreover, is much smaller than the Eurasian draft animals, and is limited to South America. North America, like Africa, had no domesticatable large mammals. Because of the north-south axis of the Americas, divided by hostile climate in Central America and southern North America, neither the llama nor the culture and technology of the various peoples could easily spread very far. Although the South American people did develop an advanced culture, without large mammals they had no incentive to develop the wheel, nor did they develop other technology. Without draft animals for plowing or transportation, the incentive for the invention of wheels and other technological developments is limited.
Asia does have some large mammals, and did develop an advanced civilization. There were times when the Asian cultures were far ahead of the European ones. Why did the Asians not sweep westward and conquer Europe? Why did they not sail around Africa? One possible reason is, again, their geography. The huge land mass is not as broken up by mountains as Europe. So it was easier for a single ruling group to dominate the entire area. When an emperor decided that there was to be no more exploration of barbarian lands, there was an end to such activity.
In Europe, however, the terrain led to there being many smaller nations. For example, when Columbus wished to go exploring, he was turned down time after time before finding a sponsor. But there was always another king to make his pitch to. And all he needed was one. And each nation had the incentive to explore and to advance in other ways, in order to outdo their rivals. This would have been impossible in Asia.
Germs: The people of the Americas, in particular, being relatively isolated, did not have the same resistance to a variety of diseases that the Europeans did. North America, in particular, being less densely populated, had very little resistance to diseases like tuberculosis and cholera, which need large groups of people together in order to proliferate. Many native American populations were almost entirely wiped out before any European settlers arrived, having been exposed, fatally, to virulent germs by passing traders and explorers. Of course, many tropical areas had diseases of their own which did, in fact, keep the Europeans at bay for a while.
Guns and Steel: The Asians, we know, did invent gunpowder, but did not use it for weapons. The Europeans, given their constant internal warfare, advanced their weaponry at every opportunity.
There is no evidence, according to Diamond, to support any idea that groups of people vary greatly in native intelligence from one part of the world to another.
So it comes down to geography. Not some magical superiority. Just geography.
