Human Evolution Research Group

Tracing the
deep roots
of humanity

We investigate the biological, cognitive, and social dimensions of human behavioural evolution — from cross-cultural cognition and child development to evolutionary demography, the origins of cooperation, and the complex systems that govern how knowledge and culture spread.

Interdisciplinary inquiry into
what makes us human

The Human Evolution Research Group is an interdisciplinary team at the School of Collective Intelligence, Université Mohammed VI Polytechnique (UM6P), Rabat, Morocco. We work at the intersection of evolutionary anthropology, cognitive science, biodemography, experimental philosophy, and complex systems to understand the biological, cultural, and social foundations of human behaviour.

Our research spans fieldwork in Bolivia, Morocco, Ecuador, Vanuatu, India, and Argentina, combining observational data, field experiments, Bayesian statistics, and mathematical modelling. We are affiliated with major long-running projects including the Tsimane Health and Life History Project and co-direct the CoDeM2 longitudinal anthropological laboratory.

Based in Africa and committed to global scholarship, we are co-organising the HBES 2026 (Human Behavior and Evolution Society) and CES 2026 (Cultural Evolution Society) conferences, and welcome prospective graduate students, postdoctoral researchers, and collaborators from across the world.

Major Collaborative Initiatives

UM6P · School of Collective Intelligence
CoDeM2 — Cooperation, Demography & Modernity in Morocco & Bolivia

A longitudinal anthropological laboratory co-directed by Dr Alami and Dr Seabright, collecting original data on cooperation, social networks, health behaviours, kinship, and economic change across two field sites undergoing economic transition: Southeast Morocco and lowland Bolivia. The project is designed to generate comparative, theory-driven data on how modernisation reshapes social structures, gender relations, intergroup dynamics, and health outcomes in small-scale communities — bringing the tools of evolutionary anthropology directly to bear on development-relevant questions in the Global South.

Tsimane Health & Life History Project

One of the world's most comprehensive longitudinal studies of human life history, health, and social behaviour. Running continuously since 2002 under the joint directorship of Michael Gurven (UC Santa Barbara) and Hillard Kaplan (University of New Mexico), the project studies the Tsimane — an indigenous forager-horticultural population of approximately 15,000 people in the Beni Department of lowland Bolivia. The project combines biomedical surveillance, economic data, and social network analysis across over 90 villages to understand ageing, reproduction, cooperation, and modernisation. Dr Alami and Dr Seabright are both long-standing members of the project team, having contributed key studies on women's status and child health, cooperative labour networks, social support, and leadership.

The Culture of Schooling

A large-scale comparative project examining how schools function not merely as sites of academic instruction but as cultural reproduction devices — transmitting values, behavioural norms, and cognitive practices across generations. Led by Cristine H. Legare (UT Austin), the project spans diverse societies across Africa, South America, Asia, and Oceania, and investigates how school quality, structure, and cultural context shape children's cognitive development, executive function, and academic achievement. Dr Erut contributed centrally to the project, including as co-author of the Oxford Handbook of Cultural Evolution chapter on schools as cultural reproduction devices and the large-scale Developmental Science study quantifying school quality across societies.

The Geography of Philosophy

An unprecedented interdisciplinary, cross-cultural investigation into whether fundamental philosophical concepts — knowledge, wisdom, and understanding — are universal across cultures or vary in meaning and importance. Led by Edouard Machery (Pittsburgh), Stephen Stich (Rutgers), and H. Clark Barrett (UCLA), the project fielded surveys, behavioural games, and qualitative interviews across ten countries and five continents, including Morocco, Ecuador, India, Japan, South Korea, Slovakia, South Africa, China, Peru, and the United States. Dr Erut contributed as a collaborator, leading fieldwork with Shuar-Achuar communities in Ecuador, where research on epistemic norms and concepts of lying revealed culturally unique views on predictions and commitments.

About the Mark

A hominin skull,
abstracted

Cranium Dome
The rounded braincase of Homo sapiens — the defining morphological trait separating our lineage from earlier hominins.
Eye Orbits
Drawn in burnt sienna — a primary feature paleoanthropologists study when classifying fossil specimens and reconstructing ancestral faces.
Nasion Point
The central dot marks the nasion — a standard cranial landmark used in craniometric analysis and fossil measurement.
Orbit Ring
The dashed inner ring suggests evolutionary time — cyclical, long-scale processes — and gives the mark a diagrammatic, field-notebook quality.
Outer Circle & Palette
The frame makes the mark work as a badge. The umber, sienna, and ochre tones reference fossil bone, excavation soil, and aged parchment.
