Peter and Rosemary Grant conducting research

Join Peter Grant FLS FRS & Rosemary Grant FRS on Wed 4 March as they discuss their landmark research on Darwin’s finches and how new species form. Peter and Rosemary are renowned evolutionary biologists, having studied these finches on the Galápagos islands since 1973.

Thanks to @eseb.bsky.social for funding our proposal for a Special Topic Network on Polygenic Adaptation. Watch out for workshops/seminars and more activities. The STN runs for several years, so we hope this innitiative can sustain the network of oldies and new members of the polygenic community!

How do bacteria deal with double costs? And how costly are unusual levels of mistranslation anyway? In short - antibiotics are more of an issue than less/more mistranslation, but the latter changes how populations deal with antibiotics. For the long story, check out our new paper!

Kudos to @pdevillemereuil.bsky.social for writing a blog post about our paper published earlier this years in the one and only @peercomjournal.bsky.social ! You want to know how genetically variable plasticity is in your fav system, and what components of reaction norm shape vary the most? Try this!

Well done @timjanicke.bsky.social and colleagues, looking good !

Medieval volcano may have indirectly sparked Europe’s Black Death Crop failures caused by eruptions possibly forced grain imports from plague-ridden regions

The Black Death was history's worst documented demographic disaster. New research shows it was also a bizarre anomaly, the unlikely result of volcanic eruptions, multiple consecutive poor harvests in Italy, a war between Genoa, Venice and the Mongols, AND a Black Sea plague outbreak. @science.org

Does #SexualSelection fuel #Speciation?

Our new #meta-analysis of comparative studies finds support for a positive relationship, but the rather moderate global effect suggests it’s not necessarily a dominant force.

Very proud to see this work highlighted by the journal! Publishing in Evolution has always meant something special to me. Congrats to the first author Sylvain Pouzet who found the energy to keep on working on his master project during his PhD.

Heritability and target size underlie differences between trait architectures: examples for three traits. Top: Height (blue) and platelet crit (red) have the same heritability per site h2/L, but height has a much higher mutational target size L. This results in many more hits for height (1533) than for platelet crit (648) (2 left panels). However, the marginal distributions of effect sizes, MAFs, and z-scores of hits are nearly identical for the two traits (3 right panels). Middle: Height (blue) and FEV1 (gold) differ in h2/L, but have similar L. Consequently, the joint distribution of z-scores and MAFs of their hits are markedly different (2 left panels), as are the marginal distributions of hit effect sizes, MAFs and z-scores (right). Bottom: After scaling by their respective , and imposing the more stringent scaled significance threshold (corresponding to FEV1) for both traits, the joint distribution of z-scores and MAFs of their hits (2 left panels) and the corresponding marginal distributions (3 right panels) are highly similar.

Genetic architectures of #ComplexTraits vary widely. @yuvalsim.bsky.social @jkpritch.bsky.social @gs2747.bsky.social &co show these diffs arise from mutational target size & heritability per site; when controlled for, all tested traits have similar architectures @plosbiology.org 🧪 plos.io/47mZXqT
