- Reposted by Andy Gardner@kztwyman.bsky.social & @andygardner.bsky.social mathematically connect the dynamics of natural selection to optimisation to provide formal justification for viewing obligately eusocial colonies as adaptive individuals in their own right—that is, superorganism: doi.org/10.1093/jeb/...

- Reposted by Andy GardnerMany of us are using LLMs in coding and scientific writing. They are very helpful tools, but we need to be thoughtful as we integrate them into our work flows to preserve accountability, voice and trust. academic.oup.com/evlett/advan.... An editorial at @evolletters.bsky.social for discussion:
- Finally on my way to #ESEB2025, a day late, following flight cancellation... Disappointed to miss 1st day of talks, but happy that S03.01 "Advances in technology..." is in @ju-morimoto.bsky.social's safe hands. Starting 10.30am, Meeting Room 129+130, with invited talk by @kokkonut.bsky.social.
- Two other members of the research group have successfully made it to @eseb2025.bsky.social ahead of me. Look out for @kztwyman.bsky.social, whose poster "A formal theory of group-level adaptation for obligate eusociality" (P01.068) is in this evening's session.
- And Chedhawat Chokechaipaisarn, whose poster "The consequences of constrained sex allocation under local mate competition" (P02.036) is in Tuesday's session. This is based on his recent paper in Journal of Evolutionary Biology: doi.org/10.1093/jeb/... @jevbio.bsky.social @eseb2025.bsky.social
- Join us for Part 2 of the "Advances" symposium today, from 11am in Room 129+130. #ESEB2025

- Very excited to share that our paper, ‘The clonality window: relatedness and the group covariance effect in the evolution of division of labour’, is out now in @journal-evo.bsky.social advances. With @andygardner.bsky.social doi.org/10.1093/evol... #OpenAccess #Evolution #Multicellularity
- Reposted by Andy GardnerIt's finally out! This paper took quite a while but I'm so excited to share now! For anyone who studies sex chromosomes, take note: we found a rare "slower X"! (dN/dS_X < dN/dS_Autos) 👀
