In this video:
Humans have been consuming animal milk products since at least 7,500 years ago, despite not widely developing the gene mutation to properly digest milk outside of childhood until around a thousand years later. The gene that facilitates the production of lactase in the human body, necessary for processing the lactose in milk- see What Causes Lactose Intolerance, typically gets switched off in adolescence. Thanks to the rise of dairy as a significant nutrition source, initially largely in cheese and yogurt-type substances that could be widely consumed due to low lactose content and had better shelf life, those who had a genetic quirk allowing them to produce lactase into adulthood flourished, and this mutation quickly spread throughout a relatively large percentage of the human population over the centuries. By 4,000 BCE (six thousand years ago), a dairy economy existed in central Europe, Asia and ancient Egypt, and with it came disease.
