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. ThanksThanks 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...
Scientists agree that dogs evolved from wolves, but exactly how and when that happened is hotly contested.

The widely-held idea known as the “obstetrical dilemma” is a hypothesis that explains why babies are so helpless, and why childbirth is so difficult for humans compared to other animals. The obstetrical dilemma suggests that babies are born early so their big brains can fit through the mother’s pelvis, which can’t get any wider due to our method of bipedal locomotion. This problem, the idea says, is solved by an evolutionary tradeoff that increases risks to pregnant mothers who must struggle to birth bigger and bigger-brained babies through narrow birth canals. On this episode, Leakey Foundation grantees Dr. Holly Dunsworth and Dr. Anna Warrener describe their search for the evidence behind the obstetrical dilemma and they discuss the importance of the stories we tell about our bodies.

What is it like to study an endangered species like chimpanzees, knowing they may go extinct within your lifetime? Leakey Foundation grantee Dr. Zarin Machanda is a co-director of the Kibale Chimpanzee Project, a long-term field study in Uganda. This study was started by primatologist Richard Wrangham in 1987, and project members have collected daily records of the chimps there ever since. These notes hold the life stories of around 150 chimpanzees, and this long-term data is a powerful way for scientists to understand chimpanzees–and ourselves.
