Lactose Tolerance And Human Evolution. In a study published today in nature, researchers compared archaeological evidence for 9,000 years of european milk use with genetics, and found an unusually rapid, evolution of lactose. In most mammals, lactase activity declines after weaning, leading to lactose intolerance. Thousands of years ago, ancient farmers gained the ability to consume milk as adults without getting an upset stomach. But now, a paper in nature has been. Lactase persistence—the ability of adults to digest the lactose in milk—varies widely in frequency across human populations. Lactose tolerance was beneficial enough to influence evolution only during occasional episodes of famine and disease, explaining why it took thousands of. Now researchers think they know why:
