Cognitive ethology studies the minds of animals in their natural environments, revealing sophisticated capacities for learning, emotion, and social complexity across diverse species.
Cognitive ethology has transformed our understanding of animal minds over the past 50 years. What were once considered uniquely human traits — self-awareness, empathy, planning, mourning — are now documented across a wide range of species. This scientific evidence undermines the assumption that animal suffering matters less because animals lack mental complexity. Advocates should ground welfare arguments in this growing body of cognitive science.
