Show Notes
2022 was another exciting year in human origins research! New fossil discoveries and ancient DNA research expanded our understanding of the past. We learned something surprising about the evolution of human speech, and new methodologies and showed promising potential to improve the future of medicine. In this episode, four Leakey Foundation scientists shared their favorite human evolution discoveries from the past year. Our guests Carol Ward, University of Missouri Sofia Samper Carro, Australian National University Kevin Hatala, Chatham University Megan Henriquez, City University of New York Links to learn more Evolutionary loss of complexity in human vocal anatomy as an adaptation for speech When less is more in the evolution of language The face of the first European found in Atapuerca Europe's oldest fossil named after Pink Floyd Meet the first Neanderthal family Genetic insights into the social organization of Neanderthals Population genetics study of Strongyloides fuelleborni The Leakey Foundation Origin Stories is a project of The Leakey Foundation, a nonprofit organization dedicated to advancing human origins research and outreach.

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! Origin Stories is a project of The Leakey Foundation, a nonprofit dedicated to funding human origins research and sharing discoveries.
