Humans have been on a remarkable journey these past 300,000 years. We started in Africa and slowly spread across the globe—crossing land bridges, sailing into the unknown, and eventually building cities and civilizations. While our primate cousins stayed where they evolved, we moved. Migration isn’t just something we did—it’s a defining trait of our species. Now, after filling the planet, we’re on the move again—not chasing new frontiers, but escaping rising seas, extreme heat, political instability, and economic stress.

The Human Journey covers this epic story in 12 half-hour lectures taught by award-winning science writer, author, and broadcaster Gaia Vince. Few presentations have the scope of this course, taking you from the Stone Age to the future, and featuring topics in anthropology, genetics, archaeology, economics, psychology, and Earth science. Throughout the course, the focus is on the unifying theme of migration.

You learn about key factors that make migration possible—like cooperation, fire, and carrying technology. These developments let us organize hunts, cook food, and transport essentials. You also explore how interbreeding with Neanderthals and Denisovans passed down genes that helped us thrive in climates where we couldn’t otherwise live. And looking ahead, you consider the great waves of migration that are now being set in motion by climate change. As a migrating species, we’ll adapt—just as we always have.
