Culturally transmitted skills created selection pressures shaping human anatomy and physiology
Evidence
Overall, cultural evolution can, and has, powerfully shaped the human genome in a variety of important ways. As we saw in chapter 5 , this culture-gene coevolutionary interaction goes well back into our species’ history, where culturally transmitted know-how about fire, water containers, tracking, and projectiles were some of the key selection pressures favoring aspects of our anatomy and physiology. — Joseph Henrich, The Secret of Our Success, 313
