The most interesting part is the one on milk, because unless it was all in form of cheese and such, they must have been massively able to drink milk. Britain is one of the three areas with highest LP prevalence in Europe.<br /><br />→ http://rspb.royalsocietypublishing.org/content/281/1780/20132372.abstract<br />→ http://www.times-series.co.uk/uk_national_news/11005072.Ancient_Britons__loved_dairy_food_/Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-55940933369396554422014-02-08T01:08:33.173+01:002014-02-08T01:08:33.173+01:00Your allele is not about lactose tolerance but abo...Your allele is not about lactose tolerance but about prevention of ill-effects of a high-fat diet, what is different (and it may even explaing their generally slim appearance). <br /><br />According to the study of Yuval Itan 2010, the East African LP genes are known at least partly and more or less consistent with the actual phenotype. What is not known is the West African LP gene, although the traditional herders of that area Wolof particularly have quite high LP phenotype (51%). In Sudan also, the predicted LP phenotype was only of 45% but the actual lactose tolerance is much higher (88%). <br /><br />Similarly Central Italians can drink milk without problem in most cases (85%) but genetics can only predict 21%. A similar case happens in Jordan. <br /><br />On the other hand Afghan Tajiks are very much lactose intolerant (only 18% can actually digest it) but genetic predictions claim 51% LP expected phenotype. There are some notorious mismatches between genetic pedictions and phenotype through the World, including some parts of Europe. <br /><br />See: http://leherensuge.blogspot.com/2010/02/actual-lactase-persistence-more-common.htmlMajuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-65736507719878144222014-02-07T21:25:39.951+01:002014-02-07T21:25:39.951+01:00As an aside, you have wondered now and then about ...As an aside, you have wondered now and then about the African version of the LP gene. The gene is the C-14010 allele, and the age estimate is "~2,700-6,800 years (95% c.i. ~1,200-23,000 years), is consistent with archeological data indicating that pastoralism did not spread south of the Sahara and into northern Kenya until ~4,500 years ago and into southern Kenya and northern Tanzania ~3,300 years ago." My source relies on Tishkoff for that proposition, probably <a href="http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2672153/" rel="nofollow">this 2007 paper.</a><br /><br />"The Maasai are a pastoral people in Kenya and Tanzania, whose traditional diet of milk, blood and meat is rich in lactose, fat and cholesterol" <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0044751" rel="nofollow">also have genes</a> that prevent them from suffering the ill effects of a high fat and cholesterol diet. andrewhttps://www.blogger.com/profile/08172964121659914379noreply@blogger.com
