Origin Stories – Détails, épisodes et analyse

Are humans the only animals that practice medicine? In this episode, two scientists share surprising observations of orangutans and chimpanzees treating wounds–their own and others'–with plants and insects. These discoveries challenge ideas about uniquely human behaviors and offer insights into animal intelligence, empathy, and the evolutionary roots of medicine.

Over 50,000 years ago on what is now the Indonesian island of Sulawesi, someone climbed a towering rock formation and painted a mysterious image on a cave ceiling. The painting shows three half-human, half-animal figures and a large wild pig. The image, dated to 51,200 years old, is now the oldest known visual story in the world. In this episode, archaeologist Adam Brumm shares the story of this incredible discovery.

Humans invest enormous amounts of time and energy into bringing up our babies. This unique investment is a fundamental part of what it means to be human. In this episode, the first in a three-part series on family relationships, researchers Sarah Blaffer Hrdy, Stacy Rosenbaum, and Amy Scott explore how our species' approach to motherhood may hold the key to some of the most important traits that set us apart from other mammals.

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.

This special episode takes you inside the world of archaeology students at Boomplaas Cave, one of South Africa’s flagship human evolution research sites. Led by Dr. Justin Pargeter, the students chronicle their field school journey through personal audio diaries, offering a candid look at the joys, thrills, and challenges of archaeological fieldwork.

Thanks to Justin Pargeter, Monique Niekerk, Asi Ntsodwa, Bacara Spruit, and all the students at Boomplaas Cave field school.

The energetics of uniquely human subsistence strategies

2022 was another exciting year in human origins research! New fossil discoveries and ancient DNA research expanded our understanding of the past. We learned something surprising about the evolution of human speech, and new methodologies and showed promising potential to improve the future of medicine. In this episode, four Leakey Foundation scientists shared their favorite human evolution discoveries from the past year.
