I've said this before ... I'm "British of WHITE Caribbean descent" - a second-generation Caribbean Brit. But the word "Caribbean" implies *black*. Although, not surprisingly, I'm not culturally Caribbean at all.

The other little problem with all this is that blackness is actually a genetic adaptation to living on or near the equator. I've not met that many, but I've certainly met some Indians (that's India, not America) who, at first glance, you would take as being black. Okay, they have other racial characteristics that show them up as sub-continentals, but that's beside the point.

(Plus, there was an article on the radio recently, I just caught the gist of it, but although it's well accepted that pretty much all non-Africans are descended from a small group of humans that crossed the African-Asian landbridge, apparently there was a relatively large REVERSE migration of Eurasians into Africa about 3000 years ago (they were farmers, as opposed to the indigenous African hunter-gathers) and most African tribal genetics have been well contaminated with Eurasian genes.)

Cheers,
Wol

More precisely, non-black skin is a genetic adaptation to *not* living in the tropics. (Our ancestors all had black skin once, after all.)

It's probably the need for vitamin D in less sunny climes that's the ultimate cause of melanin reduction.
