Origin Stories

Mary Leakey was called the "grand dame" of archaeology. She was a methodical and exacting scientist who made some of the world's most significant archaeological discoveries. In this lecture from The Leakey Foundation archive, Mary Leakey tells the story of Olduvai Gorge, the place where she found fossils that completely changed our understanding of human origins.

Show Notes The Leakey Foundation is celebrating its 50th anniversary by sharing rare, previousl...

These talks are like a time machine that lets you hear from...

A scientist solves the mystery of the only known chimpanzee civil war...thus far. In 1960, Louis Leakey sent Jane Goodall to start her study of chimpanzees at Gombe National Park, Tanzania. Her first decade of research led her to think that chimpanzees were like nicer versions of humans. But in the early 1970s, the Gombe chimp community split in two and deadly violence erupted. The cause has remai...

Origin Stories returns November 15th with more stories about how we became human.

The stories and songs of prehistoric people are lost. Their art and artifacts are all that remain of their culture. The painted caves of Ice Age Europe are the world's most famous examples of prehistoric art. What does this art reveal about the people who made it? Why did they paint those images on cave walls? What do the images mean? Jean Clottes is one of the world's preeminent prehistorians and...

Three true tales about what it's like to do field research. Kelly Stewart, Dorothy Cheney, and Robert Seyfarth share stories of gun smuggling, pet leeches, close encounters with hippos, and fan mail from one of the world's most infamous mass murderers. This bonus episode was recorded live at a Leakey Foundation Fellows event in 2016. The Leakey Foundation Origin Stories is a project of The Leakey...

For a long time, scientists have been searching for the first Homo sapiens in the Great Rift Valley of Ethiopia. The story we've been telling about the origin of our species has gone something like this: Around 200,000 years ago in East Africa, the first  Homo sapiens  emerged, splitting off from an ancestral species, possibly Homo erectus.  We had big brains and a knack for tool making. We spread...

One of the big questions in the study of human evolution is the question of how our ancestors spread across the world. Our species evolved in Africa and migrated around the world from there. Most people on earth today are mixed descendants of multiple migrations to different places. Somewhere in almost everyone's family history, whether it was last year or thousands of years ago, there was someone...

It's not every day you see a Facebook post that changes your life, but that's exactly what happened to Leakey Foundation grantee Alia Gurtov. Gurtov was checking her Facebook feed one morning and saw a post from paleoanthropologist Lee Berger. He was looking for archaeologists who were "...skinny and preferably small. They must not be claustrophobic, they must be fit, they should have some caving...

The paleoanthropologist Louis Leakey described stone tools as "fossilized human behavior." These rocks, shaped by our human ancestors and found in archaeological sites around the world, can give us clues about how ancient people lived. Archaeologist and Leakey Foundation grantee John Shea of Stony Brook University says you can learn even more by making and using stone tools yourself.   Thanks to J...

Just recently, the news media announced the discovery of a 13 million-year-old fossil ape called Alesi. This remarkable fossil was found in Kenya, and it's 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 very early evolution of apes and even shows what the common ancestor of humans and all the other living apes might...

Our new season of Origin Stories is coming soon! This is a sneak preview of the first episode.

Why do people risk their own lives to save a stranger? Why do we share food or give money to charity? The human capacity for altruism has been a puzzle for scientists since Darwin. In this episode of Origin Stories, primatologist Joan Silk explores the evolution of altruism and cooperation. In our Being Human Bonus segment, we share a story of human kindness from Erika Lantz and WBUR's Kind World....

Every animal that lives in groups has to make decisions as a group. Even a seemingly simple decision like "where should we go for dinner?" can be complicated to negotiate.    Is there a simple rule behind how humans and other animals make group decisions? Margaret Crofoot is a primatologist and Leakey Foundation grantee whose research on baboons suggests there is a rule, and it's not what you migh...

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 imp...

The Power Paradox What is power? Where does social power come from? What happens in our bodies and with our behavior when we have power and when we don't? What can we learn about lasting social power from small-scale hunter-gatherer societies? Dacher Keltner is a professor of psychology at the University of California, Berkeley, and the faculty director of the UC Berkeley Greater Good Science Cent...

Humans and our recent ancestors have been accomplished endurance runners for more than a million years. Our evolutionary history as runners partly accounts for why aerobic exercise is such a key component of human health. In this talk, recorded in July 2016, Daniel Lieberman explores how and why the human body evolved to run long distances. Daniel Lieberman is the Professor and Chair of the Depart...

Empathy has long been considered a uniquely human trait, but it's an ability that has also been observed in apes and other animals. Primatologist Frans de Waal says that examples of empathy in non-human primates and other mammals suggest that empathy has a long evolutionary history in humans.   Frans de Waal is the C.H. Candler Professor of Psychology at Emory University where he directs the Livin...

Every day for 55 years a dedicated group of researchers, students, and 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.  This episode continues the story of Jane Goodall's pioneering Gombe chimpanzee research study. Thanks to Anne Pusey, director of the  Ja...

Humans are very verbal compared to other animals. We talk constantly, and our voices can signal many things beyond the meaning of our words. The human voice is also highly differentiated between the sexes.    In this live recording of our Being Human event in February 2016, Dr. David Puts explores how studying the human voice can be a good way to gain insight into human sexual selection.   Dr. Put...
