In the fifth and final episode of our first season, Becoming Human, Professor Degroot tells the epic story of how climate change spurred the evolution of the last hominin species - including our own. He explains how ancient DNA is uncovering previously hidden chapters in this remarkable tale. He shows how industrialization and famine originally brought it to light. And he closes the season by considering the implications of the deep histories we've explored in the past five episodes. 

The Climate Chronicles is really an audio book. The complete first season gives a unique overview not only of how climate change may have created our species, but also of the history of science that revealed our origins, and the creative detective work that climatologists, archaeologists, and geneticists use to dive into the deep past.
