    Lactose Intolerance has Ancient Roots

    0
    By Alisa Fleming on February 27, 2007 In The News

    The most tolerant milk drinkers, those of Northern European decent, may be the result of dairy farming adaptations.  While just 5 to 15% of today’s Northern European population is lactose intolerant (depending on the stats viewed), it is possible that all of their ancestors from millenniums past were.

    Scientists from the University College London and Mainz University in Germany, looked for the gene that produces the lactase enzyme in Neolithic skeletons dating between 5480BC and 5000BC.  The lactase gene was absent from their DNA, suggesting that these early Europeans were lactose intolerant.

    Though some cheese fans are hoping for a “survival of the fittest” argument, in which a small group of milk tolerant individuals emerged as the dominant population, we have yet to see statistics of milk consumers outliving dairy-free ones.  On the contrary, the scientists hypothesize that it was a gene adaptation that arose after the development and expansion of dairy farming.

    The study is to be published in the Proceedings of the National Academy of Sciences
