[QUOTE="Ophiolite, post: 77664752, member: 234799"] You seem confused. Lactose intolerance is the norm in most mammals once they have weaned. Lactose tolerance evolved quite recently, possibly as an adaptation to periods of famine. I asked ChatGPT how many mutations were involved in this development. This is the response: [I]The development of lactose tolerance in humans is primarily due to a genetic mutation known as lactase persistence. Normally, the production of lactase, the enzyme responsible for breaking down lactose (the sugar found in milk), decreases after infancy. However, in populations with a long history of dairy farming, certain mutations have arisen that allow the production of lactase to continue into adulthood. One of the most well-studied mutations associated with lactase persistence is the -13,910*T (rs4988235) variant located upstream of the lactase gene (LCT). This mutation is common in populations with a history of dairy farming, such as those of European descent. Other mutations, such as -13915*G and -22018*A, have also been associated with lactase persistence in different populations around the world. These mutations result in the continued production of lactase, allowing individuals with lactase persistence to digest lactose throughout their lives. This adaptation likely provided a significant evolutionary advantage in populations where dairy farming was a major part of the diet.[/I] I would call these small changes, but terms like large and small are qualitative and context sensitive. i.e. of limited value in a technical discussion.
