Host Emily Graslie has returned.
This week Emily Graslie discusses how the formation of chemical elements in the bellies of the earliest stars made life possible.
Basically the history of all life on Earth, all the way back to single-celled microbes billions of years ago.
Emily talks about the process of human evolution, and the knack for innovation that has allowed humans to become so dominant on the Earth.
Human ancestry and genealogy.
Globalization has been in process for centuries and has had a huge effect on big history, and on collective learning; this week, Emily investigates early globalization.
