[QUOTE="Jimmy D, post: 69662114, member: 366806"] Stronger argument? Let's have a re-cap (Paraphrasing for brevity) Joshua: Show me evidence of a beneficial mutation Me: Specific mutation in SLC24A5, called A111T, is found in virtually everyone of European ancestry. Joshua: The key word here is beneficial. You claim that A111T is a mutation and that it is beneficial. Yet as a general rule people with lighter color European skin are not happy with their lighter skin. Me: [I] [/I]As people moved to areas farther from the equator with lower UV levels, natural selection favored lighter skin which allowed UV rays to penetrate and produce essential vitamin D. The darker skin of peoples who lived closer to the equator was important in preventing folate deficiency. Joshua: You are the one that is failing to show a benefit. Can you prove that African and Asian people have a vitamin D deficiency in comparison to European people? They facts pretty much blow your off the cuff theory right out of the water.

Well done mate, when your arguments have been proven wrong, rather than admit your mistakes you've resorted to the lowest of the low, wrongly accusing people of racism. Sad. [/QUOTE]
