In this episode of Talking Apes, we follow Dr. Rachna Reddy into the the African rainforest, where the laughter of chimps and the quiet rhythms of bonobo life echo deeper truths about who we are. As a biological anthropologist and co-director of the Ngogo Chimpanzee Project, Rachna’s research focuses on the social bonds that shape us across the lifespan - from infant cuddles to adolescent rebellion and elder respect.

We explore the fascinating mentor bonds between young and older chimps, the powerful role of adolescence as a second window of resilience, and what bonobo group dynamics can teach us about navigating life’s transitions. It’s a journey that spans species and the stages of life.

Rachna doesn’t just study apes, she listens to them, and in doing so helps us hear ourselves a little more clearly. Tune in for a conversation that’s as thoughtful as it is delightful.

Are we really the only "talking apes"?  Get ready for a mind-blowing episode with Dr. Adriano Reis E Lameira, one of the world’s leading experts on the evolution of speech and language! 

Dr. Lameira has spent years deep in the rainforests of Borneo, decoding the vocal mysteries of orangutans. His groundbreaking research challenges long-held beliefs about what separates us from our primate cousins. Can great apes control their voices more than we thought? Do they have the ability to “talk” in ways we've never realized? And what if the roots of language go back further than we ever imagined? 

In this episode, we dive into the fascinating world of ape communication, from Rocky the “talking” orangutan to jaw-dropping discoveries about how these incredible primates may even refer to the past! We also explore how scientific bias has shaped our understanding of what makes humans unique, and why it might be time to rethink everything.

Bipedalism - How Walking Made Us Human with Jeremy DeSilva

“The history of our lineage is filled with multiple species coexisting—this moment, with only one upright walking ape on the planet, is exceptionally rare.”

Why do humans walk on two legs when no other mammal does? And what did it cost us? From back pain to difficult childbirth, our bipedal evolution has its drawbacks—but it also shaped everything about who we are today.

In this episode of Talking Apes, we sit down with Jeremy DeSilva, a leading paleoanthropologist whose research has transformed our understanding of early human locomotion. Jeremy takes us on a journey through millions of years of evolution, from the discovery of Lucy, the famous 3.2-million-year-old hominin, to fossilized footprints that reveal a world where multiple human-like species walked side by side.

With infectious enthusiasm and a deep passion for science education, Jeremy unpacks the mysteries of how and why we took our very first steps—and why it matters today.

Why are chimpanzees in Uganda scooping up bat guano and eating it? This strange behavior, captured on trail cameras and observed over 800 times in a single year, is the fascinating centerpiece of our latest episode with disease ecologist Dr. Tony Goldberg. Tony explains how this bizarre dietary shift is linked to mineral deficiencies in the chimps’ diet, caused by the loss of raffia palm trees due to human activity. What started as a simple agricultural practice has cascaded into a complex ecological ripple effect.

But the story doesn’t end with nutrition. The bat guano, rich in minerals, also contains viruses—some closely related to deadly pathogens like SARS-CoV-2 and Ebola. Tony walks us through how this newfound behavior offers a window into the early stages of potential pandemics, with implications for both chimpanzee conservation and global health. His research shines a light on the interconnectedness of human actions, animal behavior, and disease emergence.
Join us for a captivating conversation filled with groundbreaking discoveries and urgent lessons for conservation. This episode is a must-listen for anyone curious about the unexpected ways our actions impact the natural world.
