Marc Bekoff

Ethologist

Made the emotional life of animals a serious science.

AREAS OF IMPACT
AT A GLANCE

Marc Bekoff is an American ethologist, ecologist, and professor emeritus of ecology and evolutionary biology at the University of Colorado, Boulder, who transformed the scientific study of animal emotions and cognition. Born on September 6, 1945, Bekoff has dedicated more than four decades to demonstrating that animals possess rich emotional lives—experiencing joy, grief, empathy, and a sense of fairness. Through rigorous field studies of social carnivores, particularly coyotes and domestic dogs, he pioneered research methodologies that revealed the complexity of animal behavior beyond mechanistic interpretations. Co-founder of the field of cognitive ethology with Dale Jamieson, Bekoff has authored or edited more than thirty books, including the influential "The Emotional Lives of Animals" and the Encyclopedia of Animal Rights and Animal Welfare. His work bridges scientific research and advocacy, challenging industries and institutions to recognize animal sentience in policy and practice. A former Guggenheim Fellow, Bekoff has been a tireless voice for compassionate conservation, humane education, and the ethical treatment of all species, fundamentally reshaping how science, law, and society understand our fellow creatures.

About Marc Bekoff

For most of the twentieth century, attributing emotions to animals was considered unscientific anthropomorphism—a cardinal sin in behavioral biology. Then came Marc Bekoff, a field biologist who spent thousands of hours watching coyotes play, dogs apologize, and elephants mourn their dead. Armed with meticulous data and an unflinching commitment to evidence, Bekoff did something revolutionary: he made the inner lives of animals a legitimate subject of rigorous scientific inquiry. Over a career spanning five decades at the University of Colorado and beyond, he has argued—and demonstrated—that animals are not mindless automata but sentient beings capable of joy, empathy, grief, and fairness. His work has reverberated far beyond academia, influencing animal welfare legislation, conservation philosophy, and how millions of people understand the creatures with whom we share the planet.

Early Life & Education

Marc Bekoff was born on September 6, 1945, in Brooklyn, New York, and grew up in a household where curiosity about the natural world was encouraged. From an early age, he was drawn to animals, spending hours observing birds, insects, and neighborhood dogs. This childhood fascination became a lifelong vocation. Bekoff pursued his undergraduate education at Washington and Lee University, earning a bachelor's degree, before moving to Washington University in St. Louis for graduate work. There, he completed his master's degree and Ph.D. in biology, focusing on the social behavior and communication of canids—members of the dog family.

His doctoral research, conducted in the 1970s, examined the development of behavior in coyotes, a species often misunderstood and persecuted. This early work laid the foundation for what would become a career-long interest in how animals communicate, cooperate, and experience their worlds. Bekoff's mentors encouraged rigorous observation and quantitative analysis, but he also began to notice patterns that traditional behaviorism struggled to explain: animals seemed to have preferences, moods, and social bonds that went beyond survival mechanics. These observations would eventually push him toward the intellectual frontier of animal cognition and emotion.

Career & Impact

In 1974, Bekoff joined the faculty of the University of Colorado, Boulder, in the Department of Ecology and Evolutionary Biology, where he would remain for over three decades until becoming professor emeritus. His early research focused on behavioral ecology, social play, and communication in carnivores. He conducted extensive fieldwork on coyotes in the Grand Teton National Park and other sites, meticulously documenting their social structures, play behavior, and vocalizations. Unlike many ethologists of his era, Bekoff was willing to ask questions about what animals might be feeling, not just what they were doing.

In the 1980s and 1990s, Bekoff became a central figure in the emerging field of cognitive ethology—the study of animal minds. Collaborating with philosopher Dale Jamieson, he argued that understanding animal cognition required not just behavioral data but also consideration of subjective experience. This was controversial. Many scientists feared that invoking emotions or thoughts in animals would undermine objectivity. Bekoff countered that ignoring the possibility of animal emotion was itself a bias, not a safeguard. He developed research protocols that combined careful observation with experimental design, showing that animals such as dogs and wolves engage in behaviors—like play bows and reconciliatory gestures—that suggest emotional awareness and social negotiation.

Bekoff's work on play behavior was especially groundbreaking. He demonstrated that play in canids follows rules, involves role-reversal, and requires a kind of fairness or equity to be sustained. Animals who cheated or played too roughly were ostracized. This suggested not only intelligence but also a form of moral behavior—an idea that challenged deep-seated assumptions about human uniqueness. His findings have been replicated across species and have influenced fields as diverse as evolutionary psychology, philosophy of mind, and animal law.

Beyond the laboratory and field site, Bekoff became an advocate for translating scientific knowledge into ethical action. He has served on numerous boards and advisory committees for animal welfare organizations and has been a vocal critic of factory farming, invasive research, and wildlife mismanagement. He helped develop the concept of 'compassionate conservation,' which prioritizes individual animal welfare alongside ecosystem health—a departure from traditional conservation models that focus solely on populations or species.

Signature Contributions

Bekoff's most influential contribution is arguably his demonstration that animal emotions are not only real but scientifically measurable. His 2007 book, "The Emotional Lives of Animals," synthesized decades of research and became a touchstone for both scientists and the general public. Drawing on studies of empathy in rats, grief in elephants, and joy in dogs, Bekoff argued that emotional continuity across species is an evolutionary reality. The book was endorsed by Jane Goodall and translated into multiple languages, bringing the science of animal emotion to a global audience.

Another landmark work is the "Encyclopedia of Animal Rights and Animal Welfare," which Bekoff edited in 1998 (with a second edition in 2010). This comprehensive reference brought together contributions from scientists, philosophers, lawyers, and activists, creating an authoritative resource that remains widely used in universities and advocacy organizations. Bekoff also co-authored "Species of Mind" with Colin Allen, exploring philosophical questions about animal consciousness, and "Wild Justice" with Jessica Pierce, examining moral behavior in animals.

Bekoff's concept of 'deep ethology'—an approach that integrates scientific rigor with empathy and respect for individual animals—has influenced a generation of researchers. He has also been a pioneer in humane education, arguing that teaching children to respect animals fosters broader ethical awareness and environmental stewardship.

Recognition

Marc Bekoff has received numerous honors for his scientific and advocacy work. He was awarded a Guggenheim Fellowship, one of the most prestigious awards for scholars and artists, in recognition of his contributions to behavioral biology. He has also been a fellow of the Animal Behavior Society and received the Exemplar Award from the Animal Behavior Society for major long-term contributions to the field.

In 2005, Bekoff received the Bank One Faculty Community Service Award from the University of Colorado for his outreach and public engagement. He has been recognized by multiple animal welfare organizations, including the Humane Society of the United States, for his efforts to bridge science and advocacy. His books have won critical acclaim, and he is a sought-after speaker at conferences, universities, and public forums worldwide.

Legacy

Marc Bekoff's legacy is the mainstreaming of animal emotion and cognition as legitimate, essential areas of scientific inquiry. Before his work and that of contemporaries like Jane Goodall and Frans de Waal, the inner lives of animals were largely dismissed or relegated to anecdote. Today, animal sentience is recognized in law and policy in many jurisdictions—the European Union, for instance, formally acknowledges animals as sentient beings, a shift influenced by decades of research that Bekoff helped establish.

His influence extends into courtrooms, classrooms, and conservation strategies. Legal scholars cite his research in cases involving animal cruelty and captivity. Educators use his books to teach biology and ethics. Conservationists apply his principles of compassionate conservation in managing wildlife. Bekoff has also mentored countless graduate students and early-career scientists, many of whom continue his work in animal cognition, welfare science, and conservation biology.

Perhaps most importantly, Bekoff has changed public consciousness. Through accessible writing, media appearances, and tireless advocacy, he has helped millions of people see animals not as resources or automatons but as fellow beings deserving of respect and moral consideration. In an era of climate crisis and mass extinction, his call for empathy and coexistence has never been more urgent.

IN THEIR OWN WORDS
“The plural of anecdote is data.”
“Animals are not property or things but rather living organisms, subjects of a life, who are worthy of our compassion, respect, friendship, and support.”
“Fairness is a social glue that allows individuals to live together in a group.”
