Blue Eyed Dark Skin Hunter
Have you ever seen an dark skin person with blue eye...very unlikely but according to an article by Tina Hemsnay Seay blue eyes evolved before blonde hair and pale skin. Scientists discovered the skeleton of a 7,000 year old Stone Aged man. It was founded in a cave in Spain on a site called La Braña-Arintero which is why they named the fossil skeleton La Braña 1. The DNA from La Braña 1 showed that his eyes were blue and that the pigmentation of his skin and hair were dark. With some research they noticed that the man's wisdom tooth showed evidence that he was a mix of different and unusual traits. On top of his blue eyes the hunter had curly hair which brought more evidence that he was of African descent. The African skin was suggested due to the evidence that the hunter was lactose intolerant and lacked vitamin D. The hunter was unable to obtain vitamin D from dairy due the fact that the man's small intestine was deficient in lactase and with having darker skin it produced less vitamin D.
