[QUOTE]Originally posted by Knowledgeiskey718: [QB] [QUOTE] [b]"It's striking, for example, that today around eighty per cent of southern Europeans cannot tolerate lactose even though the first dairy farmers in Europe probably lived in those areas."[/b] [/QUOTE]^^^ The above statement can possibly interpreted as the relatively recent neolithic and beyond, admixture(E3b1) Benin hbs and others, into Southern Europeans, from the Natufian farmers. But the question still stands, as to why Africans are lactose intolerant, albeit being first farmers? Maybe, since Europeans skin color is due to loss of Vitamin D in their diets, and they had to find other ways to absorb Vitamin D, Europeans developed the gene for tolerance, along with becoming fully cold adapted and acquiring pale skin? Since Africans never had to adapt to loss of Vitamin D, and were able to absorb Vitamin D from the Sun, perhaps Africans didn't drink much milk? Today Africans still drink milk, albeit being intolerant, perhaps these first farmers in Africa, just drank moderately. Not as much as Europeans, when farming was spread to Europe? [b]Dr Mark Thomas, UCL Biology, said: "The ability to drink milk is the most advantageous trait that's evolved in Europeans in the recent past. Without the enzyme lactase, drinking milk in adulthood causes bloating and diarrhoea. Although the benefits of milk tolerance are not fully understood yet, they probably include: the continuous supply of milk compared to the boom and bust of seasonal crops; its nourishing qualities; and the fact that it's uncontaminated by parasites, unlike stream water, making it a safer drink. All in all, the ability to drink milk gave some early Europeans a big survival advantage."[/b] [/QB][/QUOTE]
