Mark watched

Jim watches primates in action to see how they tackle survival challenges, revealing the clever tricks that shaped the brain's thinking. But the real breakthrough came when brains learned to be social. Teaming up with his wife, Jim investigates how relationships and friendships made people more intelligent. With AI getting smarter by the day, Jim wants to know what makes biological brains so special. Through scans, fossil discoveries and cutting-edge research, he uncovers what makes the brain so hard to emulate.
