Milk and the Mutants That Love It

The video explores the concept of lactose tolerance as a 'mutant' superpower, explaining how most of the world's population is lactose intolerant due to the natural decline of lactase production after childhood. It delves into the history of milk consumption, highlighting how early humans fermented milk to reduce lactose content. A genetic mutation, known as the lactase persistence trait, allowed some populations to continue digesting lactose into adulthood, particularly in Europe. This mutation provided evolutionary advantages in certain climates, leading to varying levels of lactose tolerance worldwide.
