> I think the article itself contains a more insightful question: "Is genetic diversity linked to linguistic diversity?" Why is that an insightful question? I wouldn't have expected a strong correlation, and from the article, there doesn't appear to be one. At the risk of being too dismissive, I thought the reasons for linguistic diversity were already well known (that is, physical and political separation and a lack of trade/communication).
