In Guns, Germs, and Steel Jared Diamond suggested that geography, botany, and zoology were destiny. Europe and Asia pressed ahead economically, and remained ahead to the present day, because of accidents of geography. They had the kinds of animals that could be domesticated, and the orientation of the Eurasian land mass allowed domesticated plants and animals to spread easily between societies. But there is a gaping lacuna in his argument. In a modern world in which the path to riches lies through industrialization, why are bad-tempered zebras and hippos the barrier to economic growth in sub-Saharan Africa? Why didn’t the Industrial Revolution free Africa, New Guinea, and South America from their old geographic disadvantages, rather than accentuate their backwardness? And why did the takeover of Australia by the British propel a part of the world that had not developed settled agriculture by 1800 into the first rank among developed economies?
