Sibling relationships can include everything from love and support–to tension, competition, and conflict. They might also play a fundamental role in the evolution of our species. In the final installment of our three-part series on family relationships, researchers Karen Kramer, Cat Hobaiter, and Rachna Reddy explore surprising new science about the role of siblings in primate and human evolution.

How did climate change impact ancient human behavior? This is one of the questions Justin Pargeter and his team are investigating at a site called Boomplaas Cave in South Africa. This site has a unique record of human presence over the past 80,000 years or so. Importantly, the site is helping researchers piece together the story of how humans adapted to rapidly shifting climates in the past. Origin Stories producer Ray Pang interviews Leakey Foundation grantee Justin Pargeter, an archaeologist and professor at NYU about his work at the site, the history and importance of the cave, and why African-led research is critical for the future of science.

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.

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.

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.
