The genetic differences we obsess over. The basis for nationalism, racism and tribal thinking emerged in just the last 70,000 years. David Reich is about to show us that the past is far stranger, more violent, and more interconnected than we could ever have imagined. 90% population replacements happened in just a few centuries in the blink of a cosmic eye. David and his team reconstructed human migration patterns and discovered ghost populations, entire civilizations that vanished without any archeological trace. These people built Stonehenge. These people crossed into the Americas. These people left no trace who they are, except for the code that lurks within each of us.
