Hunter-gatherer diets weren’t always heavy on meat: Morocco study reveals a plant-based diet

      By Zineb Moubtahij, Leiden University     About 11,000 years ago, humans made a major shift from hunting and gathering to farming. This change, known as the Neolithic Revolution, dramatically altered our diets. For decades, scientists have thought that pre-agricultural human groups ate a lot of animal protein.
