通过从一个欧洲古人的智齿中提取的DNA分析,科学家揭示出他不同寻常的基因组合:蓝眼睛、黑皮肤、微卷的深棕色头发以及乳糖不耐症(黑人以及黄种人群体中较普遍)。他的骨骼被完好的保存在海拔1500米以上寒冷的西班牙西北部,因此DNA的衰变被限制。这具骨骼属于1万-5000年前的中石器时代,正是农业和畜牧业从中东向欧洲普及的时期。有研究人员估计,新石器时代人类的活动开始由狩猎转为务农,饮食习惯改变和摄取维生素D变少,导致人类皮肤颜色逐渐变浅。
Using DNA analysis extracted from the wisdom of a European ancients, scientists unveiled his unusual genetic mix: blue-eyed, dark-skinned, slightly curled dark brown hair and lactose intolerance (more common in black and yellow populations) . His bones are perfectly preserved in the colder northwestern Spain at 1,500 meters above sea level, so DNA decay is limited. This skeleton belongs to 10,000 - 5000 years ago, the Middle Stone Age, it is the era of agricultural and animal husbandry from the Middle East to Europe. Some researchers estimate that Neolithic human activities began to change from hunting to farming, dietary changes and intake of vitamin D less, resulting in the color of human skin gradually lighten.
