Higher-order interactions shape collective human behaviour
This paper shows how higher-order social network models capture group interactions beyond pairwise ties. Using empirical data, it reveals mechanisms of cooperation, contagion and moral behaviour invisible in traditional dyadic network approaches.
Oxytocin varies across the life course in a sex-specific way in a human subsistence population
Using the largest oxytocin dataset to date from the Tsimane of Bolivia, this study shows sex-specific, nonlinear changes across the life course, linking oxytocin to reproduction, caregiving and health under conditions of energetic constraint.
Great Ape Childhoods: Social and Spatial Pathways to Independence in Bonobo and Chimpanzee Infants
Comparing wild bonobo and chimpanzee infants, this study finds similar developmental trajectories but distinct social and spatial patterns. Results show how species-specific social systems shape early independence and development in great apes.
Culture is critical in driving orangutan diet development past individual potentials
Agent-based modelling of wild orangutan behaviour shows that social learning is essential for developing adult-like diet repertoires on time. Findings indicate that orangutan diets are culturally dependent and exceed individual learning limits.
Organized twice a year, the symposium offers a platform for researchers across all career stages to share ongoing work in evolutionary anthropology. Presentations span a wide range of topics, from primate social behavior and ecological physiology to human evolution and evolutionary medicine, reflecting the diversity of research at the IEA.
Integrating Environmental DNA Metabarcoding and Remote Sensing Reveals Known and Novel Fish Diversity Hotspots in a World Heritage Area
This study brilliantly combines eDNA metabarcoding and remote sensing to uncover both known and surprising fish diversity hotspots — all in a World Heritage Area. It’s a stellar example of integrative research with real conservation power!
Inside the Society of Gorillas: World Gorilla Day 2025 With Dr Robin Morrison
Robin celebrated World Gorilla Day by speaking with Gerry Ellis on the Talking Apes Podcast. In their conversation they dive into the evolution of social systems, what gorilla families can teach us about our own, and how understanding their relationships can help protect them.
