Tackling a topic this broad seems like a massive undertaking. I wish that there was more detail for each area, or to simplify the page maybe there could be a link to a new page for each geographic area. I would love for the article to include more anthropological details. Either way, I think this topic is incredibly interesting/important deserves to be expanded.
