Milk and dairy products are an integral part of our daily lives. But when we think about how humans evolved, milk is a recent addition to our diet. Lactose intolerance is not new. We were lactose-intolerant for a long time since the dawn of agriculture and animal domestication. This changed after genetic mutations enabled us to digest milk.
Our ability to digest dairy products and derive nutrition from milk was a game-changer in the evolutionary process.
The Yamnaya, who lived in the Eurasian Steppes over 5,000 years ago, was one such culture that received a significant boost in evolution thanks to milk.
