Survival rests on inherited cultural adaptations no individual could improvise alone

Evidence

What these cases teach us is that humans survive neither by our instinctual abilities to find food and shelter, nor by our individual capacities to improvise solutions “on the fly” to local environmental challenges. We can survive because, across generations, the selective processes of cultural evolution have assembled packages of cultural adaptations—including tools, practices, and techniques—that cannot be devised in a few years, even by a group of highly motivated and cooperative individuals. Moreover, the bearers of these cultural adaptations themselves often don’t understand much of how or why they work, beyond the understanding necessary for effectively using them. — Joseph Henrich, The Secret of Our Success, 117
