Origin Stories The Leakey Foundation

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.

As a young girl, Biruté Mary Galdikas dreamed of going to the forests of Southeast Asia to study the least-known of all the great apes, the elusive orangutan. People told her it would be impossible. But, in 1971, she traveled to Borneo and started what is now the longest ongoing study of orangutans in the history of science. This is her story.
She was the third in the group of now world-famous scientists known as the Trimates—Jane Goodall in Tanzania, Dian Fossey in Rwanda, and Biruté Mary Galdikas in Borneo. The Trimates were the first women to establish long-term studies of great apes in the wild. They were all mentored by Louis Leakey.
Their work formed the basis of everything science now knows about chimpanzees, gorillas, and orangutans. And they've inspired generations of researchers and conservationists to follow in their footsteps.
Today's episode celebrates Dr. Biruté Mary Galdikas and her half-century of field research and orangutan conservation work.
About our guest
Dr. Galdikas is the founder and president of Orangutan Foundation International. She's a research professor at Simon Fraser University in Vancouver and Professor Extraordinaire at the Universitas Nasional in Jakarta. She's a 19-time Leakey Foundation grantee, and she was one of Louis Leakey's last proteges in his lifetime.

Scientists agree that dogs evolved from wolves, but exactly how and when that happened is hotly contested. In this episode, Origin Stories contributor Neil Sandell examines the evolution of the relationship between dogs and humans, and explores the journey from wolf to dog.
