Continental Axis Hypothesis
One of the most striking hypotheses in Jared Diamond’s Guns, Germs, and Steel was that technology diffused more easily along lines of latitude than along lines of longitude because climate changed more rapidly along lines of longitude making it more difficult for both humans and technologies to adapt. Thus, a long East-West axis, such as that found in Eurasia, meant a bigger “market” for technology and thus greater development.
