Origin Stories The Leakey Foundation

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.

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 second in a three-part series on family relationships, researchers Lee Gettler, Stacy Rosenbaum, and Sonny Bechayda explore how our species' approach to fatherhood may have shaped some of the most important traits that set us apart from other mammals.

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.
