As an early Christmas gift, @journal-evo.bsky.social accepted @kenstoyama.bsky.social and my paper on macroevolutionary patterns of ornament evolution in birds of paradise! 🦚 Check it out here: academic.oup.com/evolut/advan...

Do extra chromosome sets mask bad mutations? Simulations show tetraploids often carry higher genetic load than diploids, depending on dominance, demography, and drift—with important implications for fitness and conservation. academic.oup.com/evlett/artic...

How do genetic variances and covariances evolve over deep time? This paper unifies quantitative genetics and macroevolution with analytical models for G-matrix evolution on phylogenies, enabling new tests of multivariate trait evolution. academic.oup.com/evlett/artic...

Can we predict gene expression evolution? In flour beetles, transcriptome-wide selection predicts expression change, with indirect selection acting strongest on pleiotropic, network-central genes—linking co-expression architecture to adaptation. academic.oup.com/evlett/artic... Photo: Udo Schmidt

Applications close tonight at midnight Eastern!

Apply by Monday to join the important work of the Access, Inclusion, and Community Committee! Learn more about the history of the committee and their work here: www.evolutionsociety.org/aic-committe...

Inspired in this iconic Guarda course, a group of four Latin American researchers organized the South American version: #EvoSur. The masterminds behind this amazing idea: Paco Majic (Uruguay) @hhydrochaerus.bsky.social, Santi Herrera (Colombia), Caua Westmann (Brasil) and Ana Maria Agapito (Perú).

The K/Pg extinction created a buffet for open-ocean fishes. A new paper shows that Pelagiaria underwent an adaptive radiation following the extinction based on new jaw shapes to fill the vacuum @knapprew.bsky.social @evoswami.bsky.social @sternarchella.bsky.social academic.oup.com/evlett/advan...

So excited to share our new work out in @evolletters.bsky.social today! doi.org/10.1093/evle... Sexual signals and preferences for them often differ across groups, contributing to reproductive isolation. But how do new signals evolve if females already have preferences for existing ones? (1/4)

New signals thrive when females aren't picky. Relaxed pickiness allowed novel purr and rattle songs to become established in Hawaiian crickets. New work by @robinmting.bsky.social @gwelsh.bsky.social in Evolution Letters. academic.oup.com/evlett/advan...

Sick of bad dates? Try sensing their microbiome. New work in Evolution Letters by Tourani et al. found that endosymbionts change male thrips’ chemical profiles, allowing females to pick compatible partners. academic.oup.com/evlett/advan...

Don't miss the December issue of Evolution, now online! academic.oup.com/evolut/issue...

It's in print! My opinionated dive into the definition of "coevolution" is officially out in the December issue of @journal-evo.bsky.social doi.org/10.1093/evol...

Thrilled to share that @corriemoreau.bsky.social and I have a new paper out in Evolution, digging into the varied ways that extreme worker plasticity impacts genome evolution in turtle ants! Paper 📃: doi.org/10.1093/evol... Image 📸: Steven Wang, tinyurl.com/2rbjbyjh

Not sure our paper rocks as much as Katharina’s cover illustration, but we’re very delighted it was picked as ‘Editor’s Choice’ on @evolletters.bsky.social!

Check out our cover article by @timjanicke.bsky.social and colleagues about the role of sexual selection in animal speciation. academic.oup.com/evlett/artic.... The beautiful illustration is by Katharina Bóth.

Estamos muy agradecidos a quienes nos apoyaron para hacer EvoSur posible: @sse-evolution.bsky.social @eseb.bsky.social @asn-amnat.bsky.social @fcien @biologists.bsky.social

Con estudiantes y profesores de cada rincón de Nuestraamérica 🇧🇴🇵🇾🇧🇷🇦🇷🇪🇨🇨🇱🇻🇪🇨🇴🇺🇾🇵🇪, el taller EvoSur de biología evolutiva transcurrió la semana pasada con total éxito! Nos encontramos 34 personas —estudiantes, profesores y organizadores— en el balneario Playa Verde, Maldonado, Uruguay.

#paper How do organisms adapt to changing environments? Through plasticity, evolution, or a combination of both? Find out in our new paper by Alger Jorritsma, where we show which strategies evolve under different environmental conditions. @journal-evo.bsky.social academic.oup.com/evolut/advan...

Now out in Evolution @journal-evo.bsky.social Tetrapod vocal evolution reveals faster rates and higher-pitched sounds for mammals 🐘🦉🐸. Mammalian hearing likely allowed the rapid diversification of their vocalizations. Open access here: doi.org/10.1093/evol... #bioacoustics #animalcommunication
