Restless Humanity: The Epic Migrations Into the Americas, Polynesia, and... Beyond? ~ Andrés Moreno-Estrada
Episode 69
Friday, 5 December, 2025

We are a movable species. In less than 50 thousand years, Homo sapiens has penetrated practically all corners of humanity. And the story started long before trains and airplanes. This is an episode about thoese epic migrations, with a focus on the two furthest edges of the human migratory map: the Americas in the West and the Polynesian islands in the east. In the end, we discuss emerging evidence that those branches met each other -- work coming directly out of the work of my guest, Andrés Moreno-Estrada.Enjoy!DECODING OUR STORYThis is episode 3 in the "⁠Decoding Our Story⁠" mini-series, recorded live at the Salk Institute's CARTA symposium on ancient DNA.
