What lies at the core of human progress?


This episode sets the scene for all human innovation. For 3.5 million years, humans and our ancestors were stuck in the Stone Age.


We cover:

  • What were we busy with for 97% of our existence?
  • Why were we so slow at innovating?
  • How did we eventually overcome these fundamental forces?


From personal pressures to global forces, we trace the blocks on human development. The answers hold many insights for today when we think about innovation and how to make progress..


This episode is ground zero as we begin our expedition through history and the creation of our modern world.
