In this episode I sit down with my friend and colleague, cognitive scientist Dr. Nicolas Claidiere from the Center for Research in Psychology and Neuroscience at Aix-Marseille University.
Nico was on the podcast once before, in episode 30 when we recorded from the International Primatological Society's conference in Hanoi, Vietnam, back in 2014.
So let's call this a 10-year reunion!
In the episode, we talk about:
-----
“You need social learning and you need technological reasoning to get technological evolution. The question is, what evolved first and what is the most important." (Nicolas Claidiere)
-----
I found this to be a remarkable conversation about the evolution of technological reasoning, social learning and cultural evolution. It offers a reflection on the broader implications of social dynamics and cognitive science, and really highlights what incredible insights can come from one of the most innovative research labs you're likely to find out there.
I hope you enjoy the interview as much as I did! And learn a lot from it, too...

What happens when a primatologist and podcaster leaves behind an academic career in Japan to embrace a new chapter in wildlife conservation in Canada?
Crickets on the show, for one...
Join me as I share my emotional decision to move on from Kyoto University and take up the role of Senior Scientist, Wildlife Conservation at the Wilder Institute / Calgary Zoo. The challenges of uprooting my family, the bittersweet farewells to a cherished community, and the thrill of new beginnings all mixed up in this candid narrative.
The episode is one part explanation for a year-long absence from podcasting, one part call-to-action as I wrestle with where to go with the podcast from here.
We're now 9 episodes away from 100. My promise to you is that we'll get there, possibly sooner than you think. But beyond that?
That's where I need your help. Here's what you can do:
This episode is not just a story of change, but a rallying call to join me on this new path where our shared passions for wildlife and science communication can drive the PrimateCast community onward.

In today’s installment of the podcast, I’m really excited to share a fascinating conversation I had with Dr. Tecumseh Fitch about the evolution of cognition and communication.
Tecumseh Fitch is Professor of Cognitive Biology at the University of Vienna where he co-founded the Department of Cognitive Biology and plays a leading role in the radically interdisciplinary Vienna Cognitive Science Hub, where they gather biologists, psychologists, neuroscientists, and computer scientists, and mix them with linguists, philosophers and musicologists to really understand cognition and communication in its broadest sense.
But more than that, Tecumseh Fitch is an icon in the fields of cognitive biology and language evolution - he literally wrote the textbook on the The Evolution of Language. His mastery of these topics are on full display in this conversation, as are his storytelling skills.
“one way of seeing cognitive science is it’s the triumph of mentalism over behaviorism” (Tecumseh Fitch)
We ended up with a rich tapestry of insights into how language and cognition evolved, how they shape the lives of animals across the spectrum - from bees to naked mole rats to chimpanzees - and how they’ve set the scene for our own human experience.
So, if you want to hear us meander from American Civil War generals to the question of why dogs can’t dance, or find out why macaques could anatomically ask questions like “will you marry me” but to my knowledge are not known to have ever done so, then stick around for the next hour plus and I guarantee you will not be disappointed.
Other topics in this interview include:
I always learn a lot through the conversations I have for The PrimateCast, but I gotta say that this one had me cognitively locked in. I hope it does the same for you.

For this episode, I sat down in the studio with evolutionary anthropologist Dr. Laura Buck in the Research Centre for Evolutionary Anthropology and Palaeoecology of Liverpool John Moores University.
Dr. Susumu Tomiya of CICASP also joined the conversation.
After waxing on the plausibility that some ancient hominins in cold climates might have hibernated - spoiler alert! Not very - Laura describes the evolutionary and developmental processes that lead to adaptations and behavioral responses to the cold.
We talk about human cold adaptation and how they relate to those of Neanderthals, and how patterns emerge to help species thrive in thermally-inhospitable places.
Laura describes her current research, and how scientists might have overlooked a potentially critical evolutionary force among mammals: hybridisation.
We touch on the idea of genetic rescue for conservation, and whether the "grolar bear", a hybrid between grizzlies and polar bears, might - and that’s a controversial might! - might allow polar bear genes to survive climate warming in the arctic.
Laura’s work on hybridisation has focused on macaques, but she argues that what we learn from studying hybrid macaque bones can help us understand many of the mysteries of evolution.
She touches on the modern techniques used in geometric morphometrics - simply put, measuring bones in cool ways to understand evolutionary processes - including the future role of AI in the process.
Laura closes with the idea of niche construction, where it’s not only how we and other species adapt to the environments around us, but also how we change those environments ourselves, leading to the conclusion that in many ways we are responsible for our own environments of evolutionary adaptedness.

In today’s lecture, Dr. Paula Pebsworth joined us from her home in Texas to give a lecture titled “You never know where life will take you: an interdisciplinary and unconventional path”.
This lecture was extra special for me, because Paula and I were grad students together at Kyoto University’s Primate Research Institute over a decade ago, both under the supervision of Mike Huffman. I’ve missed my friend over the intervening years, along with her family - who also play a feature role in her talk - so it was wonderful getting back together for this event.
Apart from the normal dose of nostalgia that such reunions can bring, I was reminded of what we lost when the Primate Research Institute was restructured in the spring of 2022 - a place where minds met and grew together, where budding and rooted primatologists alike were mixed and incubated and sent off to do amazing things wherever life after PRI took them.
And what an interesting life Paula has had, both before and after her time in Japan. Paula is an independent scientist who has had professional roles as a Research Coordinator for Wildcliff Nature Reserve in South Africa, a Post-doctoral Research Associate and adjunct associate at the National Institute of Adv. Studies in Bangalore, India, a Scientific Coordinator at Cloudbridge Nature Reserve in Costa Rica, and a head scientist for an environmental consulting firm in Saudi Arabia.
Through it all, she has worked toward tackling the monumental challenge of managing human-nonhuman primate conflict and coexistence, the topic she spends most of the lecture covering in tantalizing detail.
But would you imagine that she started out her professional career as a chemist testing wine in the California vineyards? It doesn’t seem obvious, but Paula manages to weave this background into her studies of antiparasite strategies and self-medication in chimpanzees and baboons.
And no, she wasn’t getting her subjects drunk on wine! But you’ll have to stay tuned to find out how it all makes sense in the career of this thoughtful and innovative primatologist.
Now, Paula is just about to pack up and head over to Japan herself in a few days, for an event where she’ll be speaking about human-nonhuman primate coexistence at Kyoto University. I can’t wait to meet up with her there and catch up.
Paula has also agreed to follow this lecture up with a proper conversation for the primateCast, so stay tuned for part two in the near future. I took a lot of notes during her lecture and have a lot of things to follow up on.

In today’s origin story, Dr. Colin Chapman joined us over Zoom from his home on Vancouver Island to talk about, quote, “A Few Fun Things I have Learned Studying Primates".
Colin Chapman has a whole bunch of titles that are worth a quick once over: he is a Killam Research Fellow, a fellow of the Royal Society of Canada, a fellow at Humboldt Foundation, a Wilson Fellow, holds an Office of an Academician, Northwest University, Xi’an, China and is a Conservation Fellow with the Wildlife Conservation Society. He’s also received a humanitarian award from the Velan Foundation.
Colin recently moved to Vancouver Island University to spend more time on his conservation efforts in and around Kibale National Park Uganda, where he’s spent so many of his years as one of the world’s most prominent primatologists.
In the lecture to follow, Colin unpacks what he’s learned about primate population dynamics over 34 plus years at Kibale. He talks about deforestation, bushmeat hunting and climate change, and importantly how research can allow us to make predictions about how these anthropogenic threats might affect primates in the future.
Colin closes with a series of take home messages like how it’s ok to make mistakes along the way, how scientists in more developed nations should use our privilege to focus on capacity building to support researchers in less fortunate circumstances, and why making sure to have fun is the key to longevity as a researcher.
Other topics that come up include:
For anyone interested in hearing more from Colin, he was also on the podcast in Episode 39, where I asked him to reflect on then 26 years of research and conservation at Kibale.
We hope you enjoy this take from one of the world's leading primate scientists!

In this episode of The PrimateCast origins, we’re sharing a lecture from primatologist and cognitive ethologist, Patricia Izar from the University of São Paulo.
Pat is one of the eminent Latin American primatologists, and along with her close friends and colleagues Drs. Dorothy Fragaszy and Elisabetta Visalberghi - see episode #68 for more on this from Elisabetta Visalberghi - she’s been studying the incredible tool use behavior of robust capuchins for the past few decades.
Capuchins are one of the very few non-great ape primates that are known to commonly use tools in nature - they use stones and anvils to crack open tough nuts and aquatic invertebrates (Paywall).
Pat walks us through a series of fascinating experiments with these charismatic monkeys - who by the way you can hear make a series of audio-only cameos in the background while she shows our Zoom audience some videos. Her target? Trying to understand what they know about the tools they use and what benefits they gain from using them.
Check out a short documentary about the EthoCebus project, of which Pat is a key member.
Because of her long history of observing and experimenting with wild capuchins, she challenges the idea from laboratory experiments with captive-reared individuals that capuchins don’t understand how or why the tools they use work; a commonly held belief that, unlike humans, monkeys don’t really have a strong sense of the ‘folk physics’ underlying their behavior.
Other topics that come up:
Pat ends by talking about how this iconic behavior in capuchins can tell us a lot about the evolution of tool use in humans. By studying animals like capuchins, we can learn a lot about the kinds of conditions that are likely to have fostered this cognitively demanding behavior during our evolution.
Although she doesn’t mention it in the lecture, Pat is also a key figure in the profession and development of primatology, both locally in Brazil and internationally. She is currently the President of the

In this episode, comparative cognitive scientist Dr. Reggie Gazes and my office neighbor Dr. Ikuma Adachi.
Reggie is an associate professor of psychology and animal behavior at Bucknell University in Lewisburg Pennsylvania. She and Ikuma overlapped as trainees in the lab of Dr. Robert Hampton at the now-named Emory National Primate Research Center.
Listen to Rob in episode 20 of the podcast on mental time travel and metacognition.
In the interview here, we find out how her experiences in Rob’s lab translated into Reggie’s own approach to being a teacher-scholar at Bucknell University.
Since a large part of what Reggie does involves engaging, supporting and doing research alongside undergraduate students, I thought it fitting to ask for their input in designing the interview, which can be thought of as a sort of collaboration with them.
Along with Reggie riffing on Bunny the dog, teaching students like she trains her monkeys, and - spoiler alert! - why she won’t go to karaoke with her students, we talk at length about the nuts and bolts of doing comparative cognitive science, and particularly in the context of animals in social groups.
Some key studies done by Reggie and her lab mates that are a great primer for this conversation include her work on factors influencing touchscreen work in rhesus macaques and how social networks predict learning outcomes in capuchins.
She really gets across in our conversation just how important it is to consider the rich social lives of animals when trying to design cognitive tests and understand how they think and why.
These are the kinds of things that would really matter to individual primates living under natural conditions, so it was great hearing Reggie’s thoughts on how this type of cognitive experimentation was gaining more and more traction, despite its many challenges!
Other topics covered in the interview:

In this episode of The PrimateCast origins, we’re sharing a lecture given by wildlife biologist and conservationist Dr. Ian Redmond, OBE.
Ian is renowned for his work with gorillas and elephants in Africa. Through research, filming, ecotourism, and conservation science and activism, he’s spent over 40 years cultivating the wisdom and the network needed to inspire and incite real change.
In this lecture, Ian weaves an engaging tale around his experiences. His wonderful storytelling might make you feel, as I did, like you’re part of the story. And I think that’s one of Ian’s main points; that all of us are part of nature’s story and importantly can be part of its protectorate in lots of different ways.
His stories move effortlessly from African villagers to conservation icons to world leaders, and you get the sense that Ian is at home amongst all of them, never losing sight of the ultimate goal of protecting the planet and its diverse inhabitants.
He jokes about how he got himself to Karisoke research station to study gorillas by offering to fix Dianne Fossey’s leaky roof. And even has some fun stories about Sir David Attenborough during his filming for the iconic BBC series Life on Earth.
But its his descriptions of his time in the forests, with the gorillas and elephants, with the local people that live alongside them, which really sparks in us that sense of what might be lost if we fail to act on behalf of the Earth.
To that end, Ian leaves us with some ways to support conservation efforts, including some of the initiatives he’s been directly involved in over the years. Here’s where you might be surprised to learn about blockchains for elephants!
But it all seems to be part of the bigger picture of finding ways to assess the economic value of the ecosystem services species like elephants and gorillas provide, as the true gardeners of the forests.
It’s easy to get swept away by Ian’s easy nature, engaging rhetoric, and just his plain old dude with interesting stories vibe. But you’re going to learn a lot listening to this lecture.

In this episode, conservationist, author and founder of The Orangutan Project, Leif Cocks.
Leif is a tireless conservationist who seems to be involved in innumerable conservation projects throughout Southeast Asia, but most notably The Orangutan Project, which he founded in 1998.
We talk about Leif’s path to conservation, which began early on with an interest in animals and nature and was formalized through his experiences in higher education and work in husbandry and small population biology at Perth Zoo.
What really stands out in this conversation is Leif’s passion for and commitment to being a defender of the natural world and all the beings living in it.
We get into orangutan conservation, including what he views as the pillars of successful orangutan reintroduction - physical health, mental health, social skills, and forest skills.
Leif describes how The Orangutan Project operates, emphasizing the importance of collective action and going far beyond just orangutan conservation into preservation of entire ecosystems and supporting local human communities living therein.
He also deftly describes the real challenges involved in conserving the rainforest’s megafauna, from supporting the endearingly “bat shit crazy” folks who manage to translocate elephants to safe areas, to getting people emotionally connected to the species and ecosystems that need saving.
I really appreciated Leif’s ability to unpack the nitty gritty of running a successful conservation effort, and the efforts they’ve made to assess the progress of the various initiatives they’ve sponsored.
We close out the conversation with some moral questions about personhood in nonhumans and the value of captivity for conservation at places like zoos.
Other topics we discuss:
Notable quotes from Leif:
If you want to find out more about Leif, his personal story and his work, you can find him at leifcocks.org or through The Orangutan Project website. He’s also the author of three books: Orangutans and their Battle for Survival, Orangutans: My Cousins, My Friends, and Finding Our Humanity.
