Episode 55: Monkeys Get Creative

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. The Leakey Foundation Origin Stories is a project of The Leakey Foundation, a nonprofit organization dedicated to funding human origins research and outreach. Support Long-Term Field Research The Leakey Foundation’s Primate Research Fund helps keep long-term primate studies going no matter what. We provide emergency funding to projects facing a gap in their usual funding - or other emergencies that threaten their ability to collect data.

Episode 51: The Teeth Remember

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.

Episode 50: Understanding Neanderthals

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.

Episode 49: Exercise

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. Visit leakeyfoundation.org/live and sign up to receive event reminders.

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.

Episode 46: Interview with María Martinón-Torres

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.
