Which of the following arguments can be made against Jared Diamond's "Geography is Destiny" hypothesis?

Group of answer choices

Diamond argues that the Spanish were able to dominate the civilizations of the Americas because of their longer history of farming and consequent superior technology. But we now need to explain why the Mexicans and Peruvians inhabiting the former lands of the Aztecs and Incas are poor. While having access to wheat, barley, and horses might have made the Spanish richer than the Incas, the gap in incomes between the two was not very large. The average income of a Spaniard was probably less than double that of a citizen of the Inca Empire. Diamond's thesis implies that once the Incas had been exposed to all the species and resulting technologies that they had not been able to develop themselves, they ought quickly to have attained the living standards of the Spanish. Yet nothing of the sort happened. On the contrary, in the nineteenth and twentieth centuries, a much larger gap in incomes between Spain and Peru emerged. Today the average Spaniard is more than six times richer than the average Peruvian. This gap in incomes is closely connected to the uneven dissemination of modern industrial technologies, but this has little to do either with the potential for animal and plant domestication or with intrinsic agricultural productivity differences between Spain and Peru. While Spain, albeit with a lag, adopted the technologies of steam power, railroads, electricity, mechanization, and factory production, Peru did not, or at best did so very slowly and imperfectly. This technological gap persists today and reproduces itself on a bigger scale as new technologies, in particular those related to information technology, fuel further growth in many developed and some rapidly developing nations.

Geographic factors are unhelpful for explaining not only the differences we see across various parts of the world today but also why many nations such as Japan or China stagnate for long periods and then start a rapid growth process. We need another, better theory one based on institutions and that also explains why institutions differ systematically across countries and why they change.

The other part of the geography hypothesis is that the tropics are poor because tropical agriculture is intrinsically unproductive. Tropical soils are thin and unable to maintain nutrients, the argument goes, and emphasizes how quickly these soils are eroded by torrential rains. There certainly is some merit in this argument, but the prime determinant of why agricultural productivity agricultural output per acre is so low in many poor countries, particularly in sub-Saharan Africa, has little to do with soil quality. Rather, it is a consequence of the ownership structure of the land and the incentives that are created for farmers by the governments and institutions under which they live.

World inequality cannot be explained by climate or diseases, or any version of the geography hypothesis. Just think of Nogales. What separates the two parts is not climate, geography, or disease environment, but the U.S.-Mexico border. If the geography hypothesis cannot explain differences between the north and south of Nogales, or North and South Korea, or those between East and West Germany before the fall of the Berlin Wall, could it still be a useful theory for explaining differences between North and South America? Between Europe and Africa? Simply, no.

All of the above arguments may be made against the Diamond hyothesis.
