Origin Stories

People have been fascinated with Neanderthals since they were first discovered in the mid-1800s. For a long time, they have been seen as dumb, brutish cavemen. As more discoveries have been made in the past few decades, our picture of who Neanderthals were and how they lived has shifted dramatically. In this episode we talk with Shara Bailey, a Leakey Foundation grantee and professor at New York U...

When Kristen Hawkes first started to research the foraging habits of the Hadza hunter-gatherers, she noticed that the older women in the society were spending their time collecting food and sharing it with their grandchildren. She started to wonder if this type of contribution from grandmothers might explain why humans have such long lives. Her grandmother hypothesis suggests that grandmothering m...

Laughter is a universal human behavior. Have you ever wondered why we laugh or what it really means when we do? Greg Bryant of UCLA studies the evolution of communication and vocal behavior, especially of spontaneous vocal expressions such as laughter. In this episode of Origin Stories he explores the origins and evolution of human laughter in a talk that was recorded live at our Being Human event...

In this episode we take a closer look at the evolutionary arms race between humans and the microbes that make us sick. What does each side bring to the fight? Dr. Pardis Sabeti of Harvard University is a computational biologist who uses math and computers to look into the genomes of humans and infectious microbes to see how both humans and microbes are evolving. She was named one of TIME Magazine'...

Tuberculosis is the world's leading cause of death by infectious disease, and it has been plaguing humanity for a very long time. In the first episode of a two-part series on infectious disease and human evolution, Dr. Anne Stone of Arizona State University investigates a mysterious case of tuberculosis in ancient Peruvian mummies and finds surprising new evidence in the search for the origins of...

The bad news is that everybody has face mites. The good news is that these tiny cousins of spiders and ticks seem to be harmless for the vast majority of us.  In this episode, entomologist and evolutionary biologist Michelle Trautwein describes how she and her colleagues collected face mite DNA from a variety of volunteers for a study published in the  Proceedings of the National Academy of Scienc...

Alison Gopnik is a professor of psychology and affiliate professor of philosophy at the University of California at Berkeley. Her research focuses on how babies and young children learn about the world. She’s the author of over 100 journal articles and several books including The Scientist in the Crib and The Philosophical Baby .  This episode is part of the Being Human event series, presented by...

We humans have evolved very differently from other primates. Is there one thing responsible for humans becoming human? Some evolutionary biologists think that the way we process our food, namely cooking it, could explain why our species developed so differently from others. Did cooking make us human? Dr. Richard Wrangham of Harvard University and Dr. Rachel Carmody of UCSF and Harvard discuss the...

This episode of Origin Stories was recorded live in San Francisco as part of the Bay Area Science Festival. It was the first of The Leakey Foundation and the Baumann Foundation’s new “Being Human” event series. Our speaker was Robert Sapolsky, a professor of biology and neurology at Stanford University and a MacArthur “Genius” Fellow. He gave a fascinating and funny talk about human behavior and t...

In On the Origin of Species , Charles Darwin used a sketch of a tree of life to help describe his theory of evolution. In this metaphor, the branches of the tree represent the relationships between all living and extinct creatures. Humans, like all living creatures, are on the surface of the tree, and all extinct creatures are within the tree. In this episode we talk with Dr. Bernard Wood who stud...

For over 35 years Dorothy Cheney and Robert Seyfarth have been studying wild African primates in order to better understand the evolution of the human mind. In this episode they tell us about their long-term study of free-ranging baboons in the Okavango Delta in Botswana. Kinship and rank are tremendously important to these baboons. However, in this sophisticated society there seems to be a certai...

Have you ever wondered what it's like to make a major fossil discovery?  Arizona State University graduate student Chalachew Seyoum and professor Kaye Reed tell us their exciting story. Seyoum was working as part of a team co-directed by Reed. While searching for hominid fossils at a site called Ledi-Geraru in the Afar region of Ethiopia, he found a fossil jaw sticking out of the 2.8 million year...

Every day for 55 years a dedicated group of researchers, students, and Tanzanian field assistants have spent their days crawling through thorns and vines as they follow chimpanzees to observe their behavior. They write everything down in notes and on maps and checksheets. It adds up to an impressive amount of data.  This episode tells the story of the evolution of data collection at Gombe, what it...

Dr. Jane Goodall is a legend. She is a science hero, a trailblazing researcher who inspires people around the world. In this episode, Jane Goodall shares part of the story of how she went from working as a secretary to becoming the world's leading expert on chimpanzee behavior. In 2004, author and Leakey family biographer Virginia Morrell interviewed Jane Goodall for the Louis Leakey Centennial Or...

Hiccups are an annoyance that we all deal with, but don't usually give much thought to. In this episode of Origin Stories, independent producer Ben Nimkin brings us the remarkable story of Charles Osborne, a man who holds the Guiness World Record for the longest attack of the hiccups. He had them for 68 years! We'll hear from the doctor who treated him, and researchers who are exploring the biolog...

One of the things that makes us different from other animals is the way we move around on two feet. Figuring out how and why our ancestors first stood up is one of the big questions in the study of human evolution. Carol Ward is an anatomy professor at the University of Missouri, and she's a paleoanthropologist who studies locomotion in our earliest primate ancestors. She tells the story of one bo...

Origin Stories is The Leakey Foundation's new podcast about what it means to be human, and the science behind what we know about ourselves. Our show will explore the biology and the millions of years of evolution that shape the way we look and act today.
