Migration and skin colour
According to this article, dark skin got lighter as people migrated north. If people of light skin migrated from say northern Europe to hot sunny equatorial regions, would their skin and hair darken genetically from birth? And if so, how many years/centuries would this take. Thank you Chwyatt (talk) 12:41, 2 September 2008 (UTC)
 * that's very hypothetical, but if it did, it would take tens of millennia. It did, after all, take some 30,000 years for the skin to turn light after people migrated north. dab (𒁳) 19:47, 3 September 2008 (UTC)
 * Cheers, just wondered how long environmental factors would change human physiology Chwyatt (talk) 10:55, 17 September 2008 (UTC)Are they already sure about that? I think that is still debated. Am I wrong, or what? MrFang72
