Chimpanzee groups show that bigger can be better for sharing. New experiments reveal that tolerant groups with restrained leaders sustain shared resources longer, offering clues to the deep evolutionary roots of cooperation. #Primatology #HumanEvolution #Cooperation #BehavioralEcology

Spider monkeys do more than search for fruit. A seven-year study shows they swap “insider knowledge” by constantly reshuffling social groups, building a shared map of where and when trees ripen. Collective intelligence in action. #Primatology #AnimalBehavior #Evolution

Baby chimps take the biggest risks, not teens. A new study shows how early danger, falling bodies, and limited supervision shaped chimp behavior and may explain why humans delay risk until adolescence. #Anthropology #Evolution #Primatology #HumanOrigins www.primatology.net/p/when-baby-...

Elderly wild chimpanzees show steep, uneven declines in tool use. A 17-year study finds aging affects not just strength but cultural memory. Could this mirror aging in early hominins? #Primates #Anthropology #HumanEvolution #ToolUse #Chimpanzees

Chimpanzees in Zambia have started a new trend: sticking blades of grass in their ears and butts. It’s not grooming. It’s fashion. And it's spreading. #Primates #AnimalCulture #Chimpanzee #SocialLearning #Primatology #PrimateCulture #AnimalBehavior

New primate research shows female dominance is not an exception but a recurring pattern in species with monogamy, arboreality, and less sexual dimorphism. Patriarchy may not be as "natural" as once thought. #Primates #Anthropology #GenderRoles @pnas.org

Chimp moms with strong female friendships are more likely to raise surviving babies—even without kin. New research from Gombe reshapes how we think about social bonds and infant survival. #Primates #Anthropology #Evolution #Gombe #Chimpanzees

Why do humans "baby talk"? A new study shows we're the only great ape that does so regularly—and it may have shaped the evolution of language. #PrimateCommunication #HumanEvolution #BabyTalk #Anthropology #Linguistics #CognitiveScience @carolinefryns.bsky.social @franziswegdell.bsky.social
