Milk drinkers brought farming to Europe

The new settlers also had something of a miracle food at their disposal. They produced fresh milk, which, as a result of a genetic mutation, they were soon able to drink in large quantities. The result was that the population of farmers grew and grew.
These striking insights come from biologists and chemists. In a barrage of articles in professional journals like Nature and BMC Evolutionary Biology, they have turned many of the prevailing views upside down over the course of the last three years.
The most important group is working on the “Leche” project (the name is inspired by the Spanish word for milk), an association of 13 research institutes in seven European Union countries. The goal of the project is to genetically probe the beginnings of butter, milk and cheese.
An unusual circumstance has made this research possible in the first place. Homo sapiens was originally unable to digest raw milk. Generally, the human body only produces an enzyme that can break down lactose in the small intestine during the first few years of life. Indeed, most adults in Asia and Africa react to cow’s milk with nausea, flatulence and diarrhea.
