EHBEA 2026
Annual Conference of the European Human Behaviour and Evolution Association
[AI]Volution
The upcoming conference of the European Human Behaviour & Evolution Association will take place in Leiden, The Netherlands, 14th-17th of April 2026.
EHBEA is committed to organising genuinely interdisciplinary conferences that bring together all researchers applying evolutionary theory to the behavioural sciences, including behavioural ecology, psychology (e.g., comparative, social, developmental), ethology (e.g., sociobiology, primatology), anthropology, cultural evolution, archaeology, sociology, linguistics, narratology, medicine, and more.
On top of the regular conference, the 2026 edition features the [AI]volution theme track. With Iyad Rahwan as our dedicated keynote speaker, talks session, panel discussion, and poster area, we aim to explore the meaning of developments in artificial intelligence for research in EHBEA domains. The facets that will be explored include, but are not limited to:
-
machine behaviour and cognition;
-
hybrid/augmented human behaviour, intelligence, and cultural evolution;
-
AI-driven modelling and research support;
-
ethics and societal impact of AI.
Besides that, as part of the [AI]volution theme track we host a hands-on workshop on Tuesday the 14th in the evening (and, in case of sufficient interest, once again on the 15th) on how Large Language Models (LLMs) can be responsibly used to analyse qualitative data.
We welcome empirical and theoretical submissions adhering to high standards of scientific rigour and ethics. Our Code of Conduct can be found on the EHBEA website.
Please see our call for abstracts for more details!

SPEAKERS
Prof. Iyad Rahwan – [AI]volution Keynote
Prof. Iyad Rahwan is director of the Max Planck Institute for Human Development in Berlin, where he founded and directs the Center for Humans & Machines. He is also an honorary professor of Electrical Engineering and Computer Science at the Technical University of Berlin. Prior to moving to Berlin, he was an Associate Professor of Media Arts & Sciences at the Massachusetts Institute of Technology (MIT). A native of Aleppo, Syria, Rahwan holds a PhD from the University of Melbourne, Australia. Rahwan's work lies at the intersection of computer science and human behavior, with a focus on the impact of Artificial Intelligence and digital media on the way we think, learn, work, play, cooperate and govern. His work appeared in the world’s leading academic journals, including Science and Nature, and features regularly in major media outlets, including the New York Times, The Economist, and the Wall Street Journal. His artistic and scientific work was also featured in some of the world’s leading cultural institutions, such as Ars Electronica, Science Museum London and Cooper Hewitt Smithsonian Design Museum.
Prof. Cat Hobaiter
Prof. Cat Hobaiter is a Professor at the University of St Andrews and principal investigator of the Wild Minds Lab based in the School of Psychology and Neuroscience at the University of St Andrews. Next to her position as Reader, she spends around half the year in the field, extending her 20 years of working with primates in Uganda and across Africa. She recently established new field sites in Uganda: the Bugoma Primate Conservation Project and in Guinea: the Moyen Bafing Chimpanzee Project. Hobaiter earned her PhD from the University of St Andrews in 2011. Her research focuses on the evolution of communication and social behaviour, especially through long-term field studies of wild chimpanzees and other apes. During her PhD, she conducted the first systematic study of gestural communication in a wild ape, working in the Budongo Forest Reserve in Uganda with the Sonso chimpanzee community. This research is extended across sites and species, not only covering apes, but also other species such as elephants. Like humans, apes do not gesture or vocalize in isolation – their communication combines calls, gestures, facial expressions, and body postures. To better understand their communication and cognition, she has integrated the study of all these separate modalities into the study of communication. Through this work, she not only hopes to advance the understanding of great ape communication but also, by looking at areas of overlap or species-specific traits, she hopes to gain an understanding of the evolutionary origins of language.
Prof. Rogier Mars
Rogier is a Professor of Neurosciences at the University of Oxford and Principal Investigator at the Radboud University Nijmegen. His work focuses on the development and application of methods to compare brain organization across species. This work has enabled him and his group to study the evolution of the primate brain, showing how perceived human specialisations in social behavioral and language came about through modifications in the temporal and frontal cortex in apes and humans. More recently, they have extended their work to other mammals, including big-brained carnivores.
Prof. Anna Rotkirch
Bio Prof. Anna Rotkirch is a Research Professor and Director of the Population Research Institute in Finland. Her research on family ties, fertility and population dynamics in Europe seeks to integrate evolutionary and demographic approaches. Rotkirch currently studies childbearing cues and the role of digitalisation for fertility decline. She is co-PI of “Social networks, fertility and wellbeing in ageing populations” with funding from the Strategic Research Council of Finland, and has also served as the governmental Rapporteur on demography in Finland.
Talk: Did smartphones accelerate fertility decline? Global fertility rates have declined rapidly alongside the proliferation of smartphones and social media, yet potential causal links are underexplored. This talk examines how digital media may reshape reproductive cues — environmental signals influencing mating and childbearing — among young adults in three domains: (i) parental investment, including the bodily costs of motherhood, (ii) couple formation, such as impacts on dating and marriage; and (iii) parasocial interactions online, which may displace alloparental bonds. The theoretical drivers are contested: do we witness runaway investment, fuelled by technology, or technological mismatch, fuelled by social inequalities — or a combination of both? Empirically, studies have identified online cues that delay family formation (e.g., decline in couple stability) as well as those that bolster fertility desires (e.g., positive family portrayals), with impacts differing by demographic groups. Since younger adults—who are often unpartnered, childless, and the heaviest social media users—experience the most exposure, this group likely faces the strongest net effects, arguably contributing to if not driving the current changes in family formation.
Nicole Walasek, PhD. – Winner of the EHBEA NI Award!
Bio Nicole Walasek is a postdoctoral researcher at the Institute for Biodiversity and Ecosystem Dynamics at the University of Amsterdam in the Netherlands. She has a broad background in cognitive science, computer science, and psychology. In her research, she is interested in the evolution and development of sensitive periods – time periods during which experiences have a particularly large impact on development. She uses mathematical models to explore how different environmental conditions, such as environmental change, shape patterns of sensitive periods across development.
Talk: Modelling and testing the evolution and development of sensitive periods in changing environments An evolutionary enigma is why individuals are so sensitive to experiences at certain life stages. Most research focuses on these sensitive periods early in development. But, there is growing awareness that later stages, such as adolescence, have heightened sensitivity too. However, formal mathematical models or empirical tests on the evolution of these later-life sensitive periods are lacking—yet important for understanding human development and for predicting how animal populations will respond to rapid climate change or major adverse events (e.g., a global pandemic). My recent modeling shows that uncertainty arising from changing environmental conditions can select for sensitive periods later in life. In this talk, I will link these findings to existing empirical phenomena, and suggest ways forward for bridging theoretical and empirical research to advance our understanding of later sensitive periods.

CBEN Annual Meeting
On the 14th of April the Cognition, Behaviour, & Evolution Network of the Benelux (CBEN) will have their annual meeting. The programme (to be announced soon) features talks, posters, and discussions that are very interesting for members of the EHBEA community. It will take place in Leiden University's Pieter de la Court Building, right next to the Leiden Centraal train station and at 5 minutes by foot from the EHBEA venue, Het Pesthuis.
