The White Sands Footprints
Around 23,000 years ago, people walked along an ancient lakeshore in what is now White Sands National Park, New Mexico. The tracks they left behind have pushed back the dates of known human occupation of the Americas by thousands of years. In this episode, scientists from the White Sands team share the story of how these Paleolithic prints were discovered, identified, and dated. Part two will explore what the White Sands footprints can tell us about life at the peak of the last Ice Age.

The Not So Naked Ape: The Origins of Clothing
Humans are the only animals that get dressed every day. Clothing is one of our most important inventions, yet we rarely even think about it as a technology. Nina Jablonski joins us to explore when and why our ancestors started wearing clothes, and what that decision meant for our survival, our migration across the planet, and our sense of self.

Biruté Mary Galdikas - A Life Among Orangutans
Biruté Mary Galdikas passed away on March 24, 2026, at the age of 79. She spent more than 50 years studying orangutans in Borneo and fighting to protect them. Before she began her work, orangutans were the least understood of the great apes. She changed that. Her research formed the foundation of what we now know about orangutans. She was the first to learn what they ate, how they lived, how they moved, their long interbirth intervals, and so much more. Including the many threats to their survival. Her lifelong dedication inspired generations to care about orangutans and their forests, and to pursue careers in the field she helped shape. I had the honor and privilege of interviewing Birute Galdikas in 2021, on the fiftieth anniversary of her study. We're re-releasing this episode in her honor.

Can a Human Outrun a Horse?
This is a story about sweat, survival, speed, and the peculiar ways running may have shaped us as humans. Armed with a hydration vest, a dream, and paleoanthropologist Daniel Lieberman's endurance running hypothesis, filmmaker Nicole Teeny set out to push the limits of her own endurance. Nicole's mission takes her from the Kalahari Desert to Kansas to see if humans really did evolve to run. Along the way, she discovers humans' unusual superpower and asks, can a human outrun a horse? This episode was written and produced by Nicole Teeny. Sound designed and produced by Ray Pang. Edited by Audrey Quinn. Our host and executive producer is Meredith Johnson. Want more of this story?
