Origin Stories

In this episode, we explore five strange fossilized footprints found by Mary Leakey at the site of Laetoli in Tanzania. Decades after their original discovery, these footprints have revealed a new story about our ancient ancestors that expands our understanding of how hominins moved and interacted.

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.

What is it like to study an endangered species like chimpanzees, knowing they may go extinct within your lifetime?

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.

Early prehistorians had little more than stones and bones to work with as they tried to piece together the story of the Neanderthals, but today’s researchers work in ways that early prehistorians could never have imagined.

Archaeologist and author Rebecca Wragg Sykes' new book Kindred: Neanderthal Life, Love, Art, and Death synthesizes more than a century of research on Neanderthals – from the first Neanderthal fossil discovered, to the most up to date and cutting edge research - revealing a vivid portrait of one of our most intriguing and misunderstood relatives.

If exercise is healthy, why do so many people avoid doing it? If we're born to be active, why is it so hard to keep your New Year's resolutions about exercise? On this episode, learn about the powerful instincts that cause us to avoid exercise even though we know it’s good for us.

Dan Lieberman, author of the new book Exercised: Why Something We Never Evolved to Do Is Healthy and Rewarding, tells the story of how we never evolved to do voluntary physical activity for the sake of health, and helps us think about exercise in a whole new way. 

About our guest

Daniel Lieberman is a professor of human evolutionary biology at Harvard University, a member of The Leakey Foundation’s Scientific Executive Committee, and a pioneering researcher on the evolution of human physical activity. His research is on how and why the human body looks and functions the way it does. He has long been fascinated by the evolution of the human head but his main focus is currently on the evolution of human physical activity. He is especially interested in how evolutionary approaches to activities such as walking and running, as well as changes to our body’s environments (such as wearing shoes and being physically inactive) can help better prevent and treat musculoskeletal diseases. To address these problems, he integrates experimental biomechanics and physiology in both the laboratory and the field with analyses of the human fossil record.

In 2017, Dr. Isaiah Nengo announced the discovery of a 13 million-year-old fossil ape found in Kenya. This remarkable fossil, nicknamed Alesi, was 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 early evolution of apes and shows what the common ancestor of humans and all the other living apes might have looked like. In this episode, Dr. Nengo tells the story behind the discovery.

This episode was originally released in 2017. We're revisiting it now because Isaiah Nengo will be featured on our new web series, Lunch Break Science, on December 3 at 11 am Pacific. He will share updates on his research and exclusive footage of his recent field work in the Turkana Basin.

Variation in human skin color has fascinated and perplexed people for centuries. As the most visible aspect of human variation, skin color has been used as a basis for classifying people into “races.” In this lecture, Leakey Foundation grantee Dr. Nina Jablonski explains the evolution of human skin color and discusses some of the ways that harmful color-based race concepts have influenced societies and impacted social well-being.

Atapuerca is a place that holds the mystery of human evolution in Europe from 1.2 million years ago through recent times. You can find, in one place, the oldest human in Europe, the first murder in the archaeological record, and fossils that tell a range of stories from disturbing and grisly to tender and heartwarming. María Martinón-Torres is a Leakey Foundation grantee who is sometimes called a "detective of the dead" because she pieces together clues to learn about the lives and deaths of the people who once inhabited northern Spain.

Deep in the forests of Borneo, lives a society of hunter-gatherers who speak a language never before shared with outsiders. Until now.

The Cave Punan are the last surviving hunter-gatherers in Indonesia and they have reached out for help to save their forest home and their culture.

In 2018, Leakey Foundation grantee Steve Lansing was invited by the elected leader of the Punan in Borneo to meet the Cave Punan. He soon learned of the Cave Punan's unique song language and their urgent need to protect their forest from illegal palm oil plantations. They asked for his help to share their story and save their forest. 

Steve Lansing and his Indonesian colleagues are now working with local organizations on a plan to support the Cave Punan.

Origin Stories is the first media outlet to share their story and their songs. We hope you will share this podcast with your friends to help raise awareness of the Cave Punan and their plight.

A mysterious new human relative was discovered ten years ago from a pinky bone found in a Siberian cave. They're called the Denisovans, and people around the world carry their DNA today. Until just a few months ago, the sum total of all the fossils the Denisovans left behind could fit in the palm of your hand. Now new research is unlocking more of their secrets.

Thanks

Thanks to Bence Viola and Viviane Slon for sharing their work. 

Dr. Viola also wants to give a shoutout to his colleagues, including Anatoly Derevyanko over more than 40 years has excavated countless sites in Siberia, Mongolia, Uzbekistan, and Kazakhstan. And Michael Sunkov who now heads the excavations at Denisova.

I also want to thank Sergey Zelensky who provided the sounds of Denisova cave and the recording of the conference.

In this episode, we explore the story of Piltdown Man – one of the most notorious hoaxes in history. 

When Piltdown Man was discovered in a gravel pit outside a small English village in 1912, it was celebrated as a "missing link." The find captured the public's imagination and became world-famous. The problem was that Piltdown Man was a complete fraud. The purported fossils were actually made up of modern human bones and an orangutan mandible.

The Piltdown hoax suspects have included Sir Arthur Conan Doyle, author of Sherlock Holmes, and the philosopher Teilhard de Chardin. Now, more than 100 years later, scientists have narrowed the suspects down to a single culprit. 

Thanks to producer Leo Hornak for reporting this story.

Thanks also to Professor Chris Dean of University College, London, Dr. Isabelle De Groote of Liverpool University, Karolyn Shindler, Professor Chris Stringer of the Natural History Museum, London, and Dr. David Joyce of Clark University, who runs the excellent Piltdown Plot website.

Thanks as well to Dr. Miles Russell of Bournemouth University - author of  "Piltdown Man: The Secret Life of Charles Dawson."

And finally thanks to Dr. Hugh Cecil for his advice and encouragement.

Readings were by Luke Blackall, Angelo Hornak, and Jonathan Keates.

Raymond Dart was getting dressed for a wedding when he was given two boxes of rocks and fossils. Inside the boxes, he found the first evidence of humanity’s African origins. This episode tells the story of the 1924 discovery of the Taung Child through a never-before-released lecture by Dr. Raymond Dart.

Show Notes

The Leakey Foundation is celebrating its 50th anniversary by sharing rare, previously unreleased lectures from the Foundation’s archive.

The fourth lecture in this "From the Archive" series is by Dr. Raymond Dart, a neuroanatomist, discoverer of the Taung Child, and the person who named the genus Australopithecus.

Raymond Dart was born in Australia in 1893. He studied biology and became a medical doctor specializing in neuroanatomy. He moved to South Africa in 1922 to help establish the anatomy department at the University of Witwatersrand in Johannesburg. In 1924, as he was getting dressed for a wedding, he received two boxes full of rocks and fossils from a nearby mine. The fossils inside those boxes changed his life – and our understanding of human origins.

Dr. Dart gave two Leakey Foundation lectures. In this episode, you'll hear clips from one of them, along with the entirety of his lecture entitled "Why Study Human Origins?" which was recorded in Washington, D.C., in 1975.

In this never-before-released archival lecture from 1974, anthropologist Margaret Mead discusses the lives of women from prehistoric through modern times.

Show Notes

The Leakey Foundation is 50 years old this year, and we’re celebrating this milestone by sharing rare, previously unreleased lectures from the Foundation’s archive. These talks are like a time capsule that lets you hear from scientists in their own words and in their own voices - as they were making the discoveries that made them famous.

The third lecture in this "From the Archive" series is by Margaret Mead, the world famous cultural anthropologist and author. 

Margaret Mead was born in 1901 and she had a long and distinguished career as an anthropologist. She served as president of the American Anthropological Association and the American Association for the Advancement of Science. Among other academic appointments, she was a curator of anthropology at the American Museum of Natural History in New York City where she worked from 1926 until her death in 1978. After her death, she was awarded the Presidential Medal of Freedom by President Jimmy Carter in 1979. This award is the highest civilian honor given by the United States government

The citation on her award said - "Margaret Mead was both a student of civilization and an exemplar of it. To a public of millions, she brought the central insight of cultural anthropology: that varying cultural patterns express an underlying human unity. She mastered her discipline, but she also transcended it. Intrepid, independent, plain-spoken, fearless, she remains a model for the young and a teacher from whom all may learn."

Margaret Mead's Leakey Foundation lecture entitled “Women - Primitive and Modern” was recorded in Pasadena, California in 1974.

The second lecture in this "From the Archive" series is by Dian Fossey, the legendary primatologist who was sent by Louis Leakey to study the mountain gorillas of Rwanda. She gave this Leakey Foundation lecture in 1973, only six years after she started the Karisoke Research Center in the Virunga Mountains.

In this talk, she describes what it was like to establish the Karisoke research center, and she shares what she’d learned so far about their lives and behavior.

Carl Sagan explores the evolution of human intelligence from the big bang, fifteen billion years ago, through today in this never-before-released archival lecture.

Show Notes The Leakey Foundation is 50 years old this year, and we’re celebrating this milestone by sharing rare, previously unreleased lectures from the Foundation’s archive. These talks are like a time machine that lets you hear from scientists in their own words and in their own voices - as they were making the discoveries that made them famous.

The first lecture in this "From the Archive" series is by Carl Sagan, the renowned astrophysicist and science communicator. He gave this Leakey Foundation lecture in 1977, around the time of the launch of the Voyager 1 space probe and five months before the release of his Pulitzer Prize-winning book Dragons of Eden… A book about human intelligence and the evolution of the brain.

In this talk, he explores the origins of life on earth and shares his thoughts on how we came to have brains that can attempt to comprehend the vastness of the universe.

About Carl Sagan

Carl Sagan served as the David Duncan Professor of Astronomy and Space Sciences and Director of the Laboratory for Planetary Studies at Cornell University. He played a leading role in the Mariner, Viking, Voyager, and Galileo spacecraft expeditions, for which he received the NASA Medals for Exceptional Scientific Achievement and Distinguished Public Service. Sagan published more than 600 scientific papers and articles and was author, co-author or editor of more than 20 books. His Emmy and Peabody award-winning television series, Cosmos, became the most widely watched series in the history of American public television. The accompanying book, also called Cosmos, is one of the bestselling science books ever published in the English language. Dr. Sagan received the Pulitzer Prize, the Oersted Medal, and many other awards, including twenty honorary degrees for his contributions to science, literature, education, and the preservation of the environment.

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 remained a mystery until now. A new study by Leakey Foundation grantee Joseph Feldblum reveals similarities between the ways chimpanzee and human societies break down.

Thanks:

Thanks to Joseph Feldblum for sharing his work. Visit his website to learn more about his research.

Thanks to Jane Goodall for everything. Visit her website to learn more about her work and the Gombe chimpanzees.

The archival audio used in this episode is from The Leakey Foundation Archive. The narration in the first part of our story was recorded in 1970 for a Leakey Foundation filmstrip. The lecture audio is from a 1978 Leakey Foundation lecture entitled "Cannibalism and Warfare in Chimpanzee Societies."

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 a leading expert on prehistoric art. He has devoted his life to asking these big questions, and his insights have challenged popular assumptions about prehistoric art and how it evolved.

In this episode, producer Neil Sandell visits Clottes at his home in the foothills of the Pyrénées in France, and they journey deep into a painted cave called Niaux to see the famous Salon Noir.

This episode was awarded the grand prize in the Prix Marulić International Audio Festival in the documentary category.

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 out across the world from there. We adapted, and we alone survived.

Now a scientific discovery made by Leakey Foundation grantee Jean-Jacques Hublin and colleagues has challenged the story we tell about ourselves and pushed the date of the origin of our species back by 100,000 years.

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 who left the place they were born and set out into the unknown, looking for a new life somewhere else. For most of humankind’s time on this planet, we all did it the same way. We walked.

Paul Salopek is a Pulitzer Prize-winning journalist and National Geographic Explorer who is on an epic ten-year journey around the world on foot, tracing the path of early human migration out of Africa. Along the way he is talking with people and sharing their stories through his writing, and through educational programs for students. His project is called the Out of Eden Walk.

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 experience, climbing experience would be a bonus. They must be willing to work in cramped quarters, have a good attitude and be a team player." Gurtov had never seen a job description that fit her more perfectly.

A few weeks later she was in South Africa, inside a cave chamber strewn with ancient bones. The fossils she helped recover have changed the story of human evolution and added a strange new relative to our family tree.

Thanks to Leakey Foundation grantees Alia Gurtov and Will Harcourt-Smith for sharing their stories.

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 have looked like. In this episode, Isaiah Nengo tells the story behind the discovery.

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 impact that cooked food has had on human evolution.

This episode of Origin Stories was produced by Briana Breen and edited by Audrey Quinn. Music by Henry Nagle.

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 Center. A renowned expert in the biological and evolutionary origins of human emotion, Dr. Keltner studies the science of compassion, awe, love, and beauty, and how emotions shape our moral intuition. His research interests also span issues of power, status, inequality, and social class. He is the author of the best-selling book Born to Be Good: The Science of a Meaningful Life and of The Compassionate Instinct.

Dr. Keltner's most recent book is The Power Paradox: How We Gain and Lose Influence.

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 Department of Human Evolutionary Biology, and the Edwin M. Lerner II Professor of Biological Sciences at Harvard University. He is a member of the Scientific Executive Committee of The Leakey Foundation.

His research is on how and why the human body is the way it is, with particular foci on the origins of bipedalism, how humans became endurance runners, and the evolution of the highly unusual human head. Lieberman has published 3 books and more than 100 articles. His latest books are The Evolution of the Human Head, and The Story of the Human Body.

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 University, about our closest extinct relatives. Who were the Neanderthals? And why did they disappear?

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 may have led to many of the things that make humans different from other great apes.

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 series.

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’s People of the Year in 2014 for her role in the fight against ebola.

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 Sciences. The results of the study were surprising and further confirmed our current understanding of human migration through time.

Listen as we explore the lives of these close personal friends of ours, and learn how they may help us answer new questions about our own evolution.

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 studies our part of the tree of life. Wood tells us how scientists figure out which fossil creatures are our ancestors and which were just our close relatives.

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 certain attentiveness, perhaps an obsession with other individuals’ relationships. Is this similar to how humans create social bonds and alliances, and does personality play a part in the ability of these baboons to survive? Listen and learn how these field researchers have approached these and other questions about how natural selection shapes the primate mind.

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 old sediment. That jaw turned out to be the earliest known fossil from our genus Homo. It was around 400,000 years older than any Homo fossil found before. The discovery was published in the journal Science in March of 2015. Dr. Susan Anton from New York University tells us why this find and the time period it's from are important in helping us connect the dots in our picture of early human evolution.

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 Oral History Project. This never before heard recording covers the time in Goodall's life from 1957 when she arrived in Nairobi, Kenya, to November 1960 when she made her first groundbreaking discovery, one that changed the way we see chimpanzees as well as the way we define ourselves as humans.

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 bone and how it answered a question about how one of our most famous early ancestors moved.

This is the first episode of Origin Stories, The Leakey Foundation's monthly podcast about anthropology, human origins, evolution, and human and primate behavior. We'll explore what it means to be human and the science behind what we know about ourselves.
