    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. Origin Stories is a project of the Leakey Foundation, a nonprofit dedicated to funding human origins research and sharing discoveries. If you can, please give to support the show.

    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.  Links: Orangutan Foundation International Ways to get involved In Memory of Dr. Biruté Marija Filomena Galdikas: A remembrance by primatologist Erin Vogel Origin Stories is a project of The Leakey Foundation, a nonprofit organization dedicated to funding human origins research and outreach.
