For most of history, humans have actually been hunter-gatherers. Specifically, if we assume that “modern” humans started with the cognitive revolution about 70,000 years ago, then we’ve roughly spent 85% of our time on Earth as foragers.
It is now a largely accepted fact among historians that hunter-gatherers actually had better, healthier diets, they worked less and their lives in general were much more enjoyable. At least when you compare them to early agriculturalists. Then what made us change our minds about hunting and gathering? And why did it not happen at the same time everywhere?
