Origin Stories The Leakey Foundation

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.

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.

Learn about the evolution of our extraordinary ability to cool ourselves down. Biological anthropologist Andrew Best discusses the past, present, and future of sweat in this special bonus episode.

Producer and scientist Kevin McLean travels to an island off the coast of Panama where researchers have found an isolated group of monkeys with a creative approach to surviving in a challenging environment.

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.

Sleep is one of the defining traits of human life. It's also one of the most mysterious. Dr. Horacio de la Iglesia is a neurobiologist who's on a quest to understand how patterns of human sleep evolved. His new research shows an unexpected connection between sleep and the cycles of the moon.
