1. Despite geographical divisions, Eurasia was still interconnected landmass, as is evident by similar crops and livestock and Silk Road/Korasan Highway.
2. Inca had more than two main crops for calorie subsistence (beans, sweet potatoes, quinoa). Western Europe had various type of grain and tubers. China had soy and sorghum.
3. "More nutritious" means higher energy density in Diamond's context.
4. Diamond mentions the llama and alpaca but these do not make as adequate pack animals as oxen, camels, or horses. Sheep goats, and cattle came from the mideast/north africa route to Africa, and were not indigenous. North America never had domestically animals (except maybe the turkey, which was somewhat domesticated).
5. Genghis Khan had to rely on Chinese siege technologies. Most "nomadic" armies compromised infantry from civilized peoples (Attila's later army were mostly germanic infantry).
6. The conquest of Mexico had mainly due to the alliance against the Aztecs rather than disease and technology. But disease was a factor in the conquest of the Inca, and the devastation of the Mississippi Valley.
7. Not sure where he gets the "convoluted coastline" argument. Does China have narrow valley coastlines with mountainous buffers like Apennine, Balkan, and Iberian peninsulas?
8. Nowhere did I find Diamond made this argument. He suggests that Papua New Guineans had more knowledge of their environment than civilized peoples, but knowledge is not equivalent to intelligence.
