So are these: > In line with Diamond’s hypothesis, the researchers found that environmental barriers do indeed impact the likelihood of cultural traits being shared between societies. > “Our analyses support the hypothesis that yes, environment likely influences how cultural innovations spread, just like Diamond intuited..." > “Our study offers one quantitative realization of Diamond’s arguments and not a definitive answer,” Meaning, not a definitive no, either. > “Our findings point out that geography, like genetics and ecology, matters, but it is not destiny.” It's complicated. I hope this doesn't surprise anyone.
