The <strong>Bajau</strong> (sea nomads) spend 60% of their working life underwater. The <strong>Turkana</strong> (desert survivors) live on 80% animal products with almost no water. The <strong>Andeans</strong> drink water with 20 times the safe arsenic level.</p> <p>Culture and tech remove that pressure before genes can catch up. Both are evolution trajectories, but they optimize for different <strong>reward functions</strong>.</p>
