Interesting.

But I couldn't help but notice this: Why do African-Americans have a higher rate of lactose intolerance than people from where their ancestors largely come from?

[Vulpix]

I think their ancestors come mainly from the "red zones". I seem to recall there are farming tribes in Africa who have developed some kind of lactose tolerance.

Wiki says:

The Atlantic slave trade, also known as the transatlantic slave trade, was the trade of African people supplied to the colonies of the New World that occurred in and around the Atlantic Ocean. It lasted from the 16th century to the 19th century. Most slaves were shipped from West Africa and Central Africa and taken to the New World.

That does make it quite curious, since much of those two areas are green zones.

Maybe these zones were just hubs with slaves taken from rivaling tribes in the south? Or maybe lactose intolerance is a result of heavy cross-breeding, which I dare say American negroes are a result of.

What I find interesting is how clear France is cut in half.

Yeah, it's too bad there's no data on most of the Mediterranean areas to see where that stems from.

And no data on Canada which is utterly strange. Yet here it seems that every second person you talk to of Northern European heritage is lactose intolerant. I don't understand.

BS. Lactose intolerance is extremely rare here.
