So yes, we need more genetic studies of these people so that we can better understand how their pigment systems work.If it seems when you’re driving at night that you struggle to see - no matter how much cleaner you spray on the windshield - the problem may not be on the glass.Įveryone has more trouble seeing at night or under dim lights, but that struggle also could indicate that you need to update your glasses prescription, or that you have another condition. Nina Jablonski: Yes, and many of these seafaring peoples are naturally very dark and they have an excellent potential for making more pigment in their skin. Their dark hair, we're not exactly sure, but almost certainly the dark hair of eastern Asian peoples was a consequence of small population effect: the genetic drift in the ancestors of all East Asian Peoples.Ĭhris Smith: So, Nina, with that in mind, do you also see increased pigmentation or re-pigmentation amongst seafaring people, because, of course, they'll get the incident radiation off the water surface? So their dark skin actually protects them from this high amount of UVA radiation. Now the dark skin is very interesting, because the Inuit experience very, very, high levels of reflected ultraviolet radiation - long wavelength ultraviolet radiation - from the snow. Swedes evolved lightly-pigmented skin and light eyes and, due to a different set of genetic changes, people living at the same latitude, the Inuit people, in far North Eastern Asia and in Alaska have actually darker skin than we would predict, and dark hair.
