When I came across this word it got me thinking about  how as globalization and the information age permeate even some of the most remote places.  I believe our anthropology colleagues would say that culture historically has been largely an allopatric phenomenon.   People who live in close proximity have historically been more likely to share values, traditions and rituals, and have a share view of their world.  Travel, first by boat and carriage, then automobile followed by airplane, began to slowly break down the allopathic nature of things—or perhaps redefine them?   We see in the US that internet information echo chambers are beginning to revision the definition of geography.   Will this eliminate the allopatric nature of culture or simply redefine it?
