Years ago Quote by Adam Rutherford
““it’s hard to see what the evolutionary advantage might be for lactase persistence in the absence of a regular supply of fresh milk. And so we think of this as a classic example of how we have invoked shifts in our genome with our own practices—a gene-culture coevolution—experienced only in communities that were practicing dairy farming with domesticated milky beasts. What advantage having both access to milk and the ability to process it might seem obvious: In fact, it’s really the realm of intelligent but speculative guesswork. A regular supply of nutritionally rich food is one; avoiding the boom and bust cycles of seasonal crops is another possibility. By 6,000 years ago, milk had become a part of Neolithic life.””

Lactase persistence evolved alongside dairy farming, showing gene‑culture coevolution; the advantage may be nutrition and stable food supply.
In simple terms: Genes and culture co‑evolve; dairy farming drove lactase persistence.

If you look at it from one point of view, as he himself says, his monastic position of forbearance and nonviolence hasn't reaped any…” quote by Pico Iyer](https://sms4smile.com/quotes/img-quotes/9fe/pico-iyer-1252_benefits_the-dalai-lama-told-me-some-years-ago-i_678.jpg)
