Thanks for listening to Origin Stories! We are on hiatus as we work on new episodes. Our new season will launch in August, and we can't wait to share more stories about how we became human.

May 17, 2022

In this episode, we explore five strange fossilized footprints found by Mary Leakey at the site of Laetoli in Tanzania. Decades after their original discovery, these footprints have revealed a new story about our ancient ancestors that expands our understanding of how hominins moved and interacted. 

Thanks
Thanks to Dr. Ellison McNutt and Dr. Charles Musiba for sharing their work. 

Thanks as well to Jim Carty and Pat Randall for generously sponsoring this episode. Jim is a long-time Leakey Foundation supporter who actually volunteered to work at Laeotli in the 1980s to help figure out a way to preserve the Laetoli footprints.
