Origin Stories

What does evolutionary science tell us about what we should eat? In this episode, Harvard paleoanthropologist and author Daniel Lieberman joins us to discuss food, health, human evolution, and his new book, "Fed Up: What Evolution Reveals About Food, Diet, Health, and Eating Well."

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 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.

This episode features two stories from the Science Podcast. First, Science writer Ann Gibbons tells the story of three ancient hominin species that lived side-by-side in South Africa's Cradle of Humankind. Then, anthropologist Melanie Beasley discusses her new study on why chemical signals in Neanderthal teeth and bones make them look like hypercarnivores. Her research suggests they were just eating a lot of maggots!

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.

After 10 years of exploring the stories behind breakthrough science, it's time to tell our own origin story! In this special anniversary episode, we're flipping the script to share how Origin Stories began. Join us behind the scenes, revisit three milestone episodes, and get an exciting update on the Punan Batu community's fight for their ancestral lands in Borneo.

Here's to our listeners who've made this decade of science and storytelling possible, and to many more stories ahead.

Shanidar Cave is a unique archaeological site in Kurdistan where scientists found the remains of 10 Neanderthal men, women, and children. Some of these individuals had survived serious injuries, and one seemed to have been buried with flowers beneath his body. The discoveries at Shanidar challenged long-standing ideas of who Neanderthals were and what separates our species from theirs. Now, more than 50 years after the original excavations, scientists have returned to Shanidar to answer lingering questions about the Neanderthals who lived and died there.

In this episode, we celebrate the 50th anniversary of the discovery of Lucy, one of the most iconic and important scientific discoveries ever made. Paleoanthropologist Don Johanson tells the story of his early scientific career and the pivotal moment when he discovered 3.2 million-year-old hominin fossils in Ethiopia's Afar region. It's a story that connects us to our deepest roots and shows how one remarkable fossil changed our view of what it means to be human.
