Rounded off the CBEN & @ehbea.bsky.social conferences in Leiden with a bike ride to the coast, running into some fine floral displays on the way

First time in Leiden, and my first academic talk at @ehbea2026.bsky.social. Grateful to @ehbea.bsky.social for the Student Travel Grant and for a conference and community that was genuinely welcoming 🧵

Worried about the pricy hotels in Zurich? No problem, “couch surfing” is there! #ehbea2027

Can I camp somewhere beside the Zurichsee?? ⛺️

@brunelcce.bsky.social was well-represented at #ehbea2026. @replicatedtypo.bsky.social presented on ‘The cultural evolution of problem-solving’ and @abbeyepage.bsky.social on ‘When the village predicts the next baby: post-natal social support and fertility intentions in the UK’ (sadly no pic)

Here’s Matt presenting that #ehbea2026 poster on ‘Sentiments, respect and the evolution of norm psychology’ (and the conference dinner location truly was gorgeous!)

Poster presentation at EHBEA 📊

I presented a poster on the underlying social, structural, and demographic drivers of economic-based support in a small-scale fishery of the Pantanal region in Brazil.

A wonderful experience meeting the EHBEA community in Leiden for the first time.

I am sincerely grateful to be awarded the EHBEA Student Grant, which covered my travel, accommodation, and attendance fees.

Special thanks to the expert team of organisers — you know who you are @ehbea.bsky.social!

@ehbea2026.bsky.social that's a wrap! Amazing first @ehbea.bsky.social conference for me, full up with great talks and conversations, and scenery!? Did not expect a postcard beach sunset in Leiden 🤩

Had a wonderful time, thank you for having me!

Last day of conference!

We had a wonderful day with amazing talks from @nicolewalasek.bsky.social and @nakedprimate.bsky.social !

We also had our Annual General Meeting, with a big round of applause for the Organising Committee and last words from @rebeccasear.bsky.social as president.

Slide with a photo of a driver heading towards a bright dawn sun

Closing slide with a quote from Douglas Adams "...I may not have gone where I intended to go, but I think I have ended up where I needed to be....

Awesome plenary from @nakedprimate.bsky.social at #ehbea2026, about gestures and storytelling, which started with a dawn drive in Chad and ended with a Douglas Adams quote perfectly encapsulating the process of science

It was really nice to attend the @ehbea.bsky.social and share the first results from my PhD project.
It’s always good to connect with and learn from such talented and friendly people. #ehbea2026

Title slide: Modeling and testing the evolution and development of sensitive periods in changing environments

Fabulous, wide-ranging plenary from @ehbea.bsky.social’s 2026 New Investigator winner Nicole Walasek at #ehbea2026. Her work on the evolution and development of sensitive periods highlighted the benefits of multi-species work and the importance of formal modelling of verbal theories 👏👏

Photo of conclusion slide Extreme differences in selectivity (e.g,, in dating apps) between men and women do not necessarlly reflect proportional differences in sexuality / dating goals They are a consequence of feedback on dynamics that operate on: • differences in sexuality ratios and//or • possibly small differences in dating goals

Interesting presentation from Alexandros Gelastopoulos at #eheba2026 suggesting that the large difference in attention men and women get on dating apps may be an artefact of feedback dynamics that create large differences even if the underlying behaviour of groups is relatively similar

Great job by my PhD student Hannah Goodman presenting her work on the role of sexual selection in cross-cultural variation in extrasomatic ornamentation at #ehbea2026

Thank you so much tor inviting me to represent @manyprimates.bsky.social at #ehbea2026. A bit intimidating but very enjoyable to give my first talk as network co-coordinator.

Great panel discussion on team science and big datasets in comparative cognition at #ehbea2026

There is a fully-funded PhD position at the Max Planck Institute for Evolutionary Anthropology to pursue dissertation research among the Mayangna of Nicaragua, expanding a longitudinal study of subsistence strategies and behavioral ecology. Please share the posting!

Second day of @ehbea2026.bsky.social done!

Full day, full of nice discussions, a wonderful talk from Anna Rotkirch, a fruitful panel discussion about AI and science, and poster session!

Looking forward for tomorrow! 👀

#ehbea2026

Had a fab time presenting my poster at @ehbea2026.bsky.social thanks to all the people who stopped and chatted! @ehbea.bsky.social

Opening slide Progressing the causal revolution: a case study in causal re-evaluation of applied evolutionary anthropology Sarah Myers (BirthRites MPI-EVA) Sarah Johns (University of Kent)

Closing slide Conclusions • Do a DAG * Be transparent about your assumptions • Don't report odds ratios * Pay attention to measurement error * Be more self-reflecting

Fantastic example of intellectual humility from @drsarahmyers at #ehbea2026, re-evaluating a previously published paper of her own using more robust methods. Advice to the audience: “be more reflective”

STARTING NOW!

The event organised by @w-plus-ebs.bsky.social to discuss (over a drink 🍷) about empowering women and sexual and gender minority voices in #EvolutionaryBehaviouralSciences

If you’re part of @ehbea2026.bsky.social or just want to spot by, join us at Lab 071!

Finishing the first day of @ehbea2026.bsky.social in Leiden!

We had some very great talks and interesting discussions, including talks from Rogier Mars and @iyadrahwan.bsky.social

#ehbea2026

Very exciting news @ehbea.bsky.social!

Great talk by @jingyux.bsky.social bringing the collective behaviour vibe to #ehbea2026 !

Stay tuned to her beky account for the upcoming preprints on her talk on social learning + social networks
