The video discusses lactose intolerance and lactase persistence, exploring why some human populations continue to produce lactase into adulthood. It examines the evolutionary background of lactase activity in mammals, the role of agriculture in milk consumption, and the nutritional benefits of milk. The video highlights the evolutionary advantages of lactase persistence, particularly in calcium absorption and bone health, and compares it to skin pigmentation changes due to migration.
