why did ingenuity and innovation spread more efficiently between peoples in europe and asia than in america? (p. 11)

• eurasia was spread out on an east-west axis as opposed to americas north-south axis
• river systems such as the rhine and the tigris & euphrates made travel easier in eurasia than americas amazon and mississippi systems
• the roman empire connected and consolidated diverse peoples and landscapes forming an ancient network of roads and uniformity of languages unmatched in other parts of the world
• forbidding climate and a second ice age around 1500 bce led to small population growth in the americas compared to eurasia which was spared this natural calamity

clear selection

Explanation:

This question relates to the geographic and historical factors shaping the spread of innovation. The key factor highlighted in academic discussions (such as in Jared Diamond's work) is the East-West axis of Eurasia, which allows for shared climate zones, easier movement of crops, animals, and ideas, unlike the Americas' North-South axis which has drastic climate and environmental barriers that slow diffusion. The other options are either incorrect or secondary factors: river systems in the Americas were also extensive, the Roman Empire was a regional (not pan-Eurasian) network, and there was no second ice age around 1500 BCE in the Americas.

Answer:

• Eurasia was spread out on an East-West axis as opposed to America's North-South Axis
