为什么天生黑发的白种人如此少见?

评论翻译Yamulamba PretoriusA White person can have black hair. The highest frequency of black-haired Whites is found in Southern European countries. For example among Italians, 31% are black-haired, though in Portugal, black hair is less common than in Italy. Nevertheless, black hair becomes less and less common as one reaches Northern European populations. For example less than 3% of the Dutch and Irish have black hair. Oftentimes, in Northern Europe, dark brown hair is called “black hair”. Dark brown hair isn’t black hair. Many Scottish, Irish who are said to be “black-haired”, actually are dark brown-haired!一个白人可以有黑色的头发。在南欧国家，白种人的黑头发频率最高。例如，在意大利，31%的人是黑头发，尽管在葡萄牙，黑头发比在意大利要少。然而，在北欧人口中，黑头发变得越来越少。例如，只有不到3%的荷兰人和爱尔兰人有黑头发。在北欧，深棕色的头发通常被称为“黑发”。不过深棕色的头发不是黑色头发。许多被称为“黑头发”的苏格兰人和爱尔兰人实际上是深棕色的头发!一个有着完美橄榄色皮肤的黑头发伊比利亚人拉斐尔·纳达尔

与之形成对比的是肤色苍白的北欧威尔士孩子

Yamulamba PretoriusMost of the dark hair in North, West, East Europe is dark brown not black.在北欧、西欧和东欧，大多数深色头发是深棕色而不是黑色。Erick FreitasThere is no such thing as natural black hair. Even the blackest hair is just a very dark shade of brown.没有所谓的天然黑发。即使是最黑的头发也只是非常深的棕色。José María TrevijanoTo the Spanish-trained eye, it is evident most of those beautiful children pictured above in your comment with Nadal are from Northern Africa, of the Berber/Amazigh etnia and not Spanish kids.Spanish children are mostly rooted in the pre-roman population of Europe, mostly the ancient non-Indo-Europeans population the Iberians and Basque plus the more recent Indoeuropean Celts.对于西班牙有眼力劲的人来说，很明显，上面你在评论里的那些漂亮的孩子大多来自北非的柏柏尔/阿马齐格埃特尼亚，而不是西班牙的孩子。西班牙儿童大多植根于欧洲的前罗马人口，主要是古代的非印欧人——伊比利亚人和巴斯克人，再加上后来的印欧凯尔特人。

In addition, there is since several centuries ago a minority rooted in India and fierce of their race and traditions that are the Gipsys, who entered into Europe about a millennia ago and who are also Spanish adding a lot to Spanish culture, mainly in music and dance with Flamenco. But you should not confuse Spanish Celtiberians either with Spanish Gipsies or with Berbers from Northern Africa. Or with any of the new arrivals of ethnic people from Africa or Asia that are entering into Europe, mainly from Muslim countries.Then in Spain, there is a lot of sun during spring and summertime. We are social people who live outdoors not indoors or as if just leaving a hospital after a year, so we try to get our suntanned skin which we love once spring comes after winter, flooding beaches and mountains, as for us suntan skin is a healthier and much more attractive look than some kind of sick pale white skin color.此外，几个世纪前，有一个源于于印度的少数民族，他们的种族和传统是吉普赛人，他们大约在一千年前进入欧洲，他们现在也是西班牙人，为西班牙文化增添了很多色彩，主要是弗拉门戈音乐和舞蹈。但你不应该把西班牙的凯尔特人与西班牙的吉普赛人或北非的柏柏尔人混淆。或者是与来自非洲或亚洲的新移民混淆，他们主要是从穆斯林国家进入欧洲的。在西班牙，春天和夏天有很多阳光。我们是生活在户外而不是室内的社交人群，或者就像刚出院一年那种一样。所以，我们试图让我们的皮肤晒黑，我们喜欢冬天过后的春天，延绵不绝的海滩和山脉，对我们来说，晒黑的皮肤比某种病态的苍白的皮肤颜色更健康，更有吸引力。Below you will find more pictures of children of my region in Northern Spain, the Basque Country in wintertime. They are pale only due to winter festivities when the pictures were taken, except a couple of them. Under the Spanish sun, we get suntanned color acquiring our “perfect olive complexion” in a way people of Nordic countries cannot get (not sure about this because I have seen nordic people tanned as hell living in Spain’s Costa del Sol) as our skin melatonin allows it. In Southern Spain, there is sun most of the year so they remain suntanned but they are similar to the rest of the Spaniards, who are genetically one of the most homogeneous populations of Europe.下面你会看到更多我所在地区、西班牙北部巴斯克地区的孩子们的冬季照片。只有在拍摄冬季庆典的时候，他们的脸色才显得苍白。在西班牙的阳光下，我们被晒黑了，获得了我们“完美的橄榄色肤色”，这是北欧国家的人无法得到的(我不确定，不过我看到北欧人跑西班牙的太阳海岸来晒黑)，因为我们的皮肤褪黑激素允许它。在西班牙南部，一年中的大部分时间都在阳光下，所以他们一直被晒得黝黑，但他们和其他西班牙人相似，他们是欧洲基因上最同质的人群之一。
