Host Eric Garza invites listeners on a deep time walk that explores the energetics of human evolution and human development. He begins this journey as our lineage parts ways with ancestors of today's chimpanzees (Pan troglodytes), taking us through the development of stone tools, the harnessing of fire for warmth and cooking, the crafting of spears, clothing, and bows and arrows, and lastly more modern technologies designed to harness exosomatic energy sources often derived from fossil fuels.
