Join renowned energy and sustainability expert, Richard Heinberg, as he describes the flow of power in hunter-gatherer communities of the Pleistocene. As people learned to wield fire, deploy an array of tools, and coordinate actions through increasingly descriptive language, they became more capable of concentrating power. This development produced mind-blowing impacts on brain capacity and other aspects of human evolution. As you go back in time to the dawn of civilization, you'll become familiar with self-reinforcing feedback loops and how they shaped humanity's rise to dominance. And finally, you'll get to hear about (and appreciate) the surprising power of beauty in all its varied forms, but especially in the form of music. For more information, please visit our website.
