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 ...
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.
This story was originally produced for the CBC program IDEAS.

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 trade...
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.

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 aroun...
Your life story is hidden in your teeth. The days, weeks, years, and stressful events of your life are recorded in tiny timelines that can be read by scientists like Leakey Foundation grantee Dr. Tanya Smith.
She and her colleagues used fossil teeth to tell a detailed and intimate story about the lives of two Neanderthal children and the changing world they lived in.

If exercise is healthy, why do so many people avoid doing it? If we're born to be active, why is it so hard to keep your New Year's resolutions about exercise? On this episode, learn about the powerful instincts that cause us to avoid exercise even though we know it’s good for us.
Dan Lieberman, author of the new book Exercised: Why Something We Never Evolved to Do Is Healthy and Rewarding, tells the story of how we never e...
In 2017, Dr. Isaiah Nengo announced the discovery of a 13 million-year-old fossil ape found in Kenya. This remarkable fossil, nicknamed Alesi, was from a time period where there’s a big blank spot in the fossil record of our family tree. Alesi tells us something new about the early evolution of apes and shows what the common ancestor of humans and all the other living apes might have looked like. In this episode, Dr. Nengo tells th...
Variation in human skin color has fascinated and perplexed people for centuries. As the most visible aspect of human variation, skin color has been used as a basis for classifying people into “races.” In this lecture, Leakey Foundation grantee Dr. Nina Jablonski explains the evolution of human skin color and discusses some of the ways that harmful color-based race concepts have influenced societies and impacted social well-being.

Deep in the forests of Borneo, lives a society of hunter-gatherers who speak a language never before shared with outsiders. Until now.
The Cave Punan are the last surviving hunter-gatherers in Indonesia and they have reached out for help to save their forest home and their culture.
In 2018, Leakey Foundation grantee Steve Lansing was invited by the elected leader of the Punan in Borneo to meet the Cave Punan. He soon learned of the...

Hosted by Laura Beil (Dr. Death, Bad Batch), Sympathy Pains is a six-part series from Neon Hum Media and iHeartRadio. For 20 years, Sarah Delashmit told people around her that she had cancer, muscular dystrophy, and other illnesses. She used a wheelchair and posted selfies from a hospital bed. She told friends and coworkers she was trapped in abusive relationships, or that she was the mother of children who had died. It was all a con. Sympathy was both her great need and her powerful weapon. But unlike most scams, she didn’t want people’s money. She was after something far more valuable.
