#SexChromosomeEvolution #SexChromosometurnover #Meiosisrecombination #SexSpecific

Sex chromosome stability and turnover across vertebrates: a developmental gene regulatory network perspective Sex chromosomes have evolved repeatedly across the Tree of Life, yet their evolutionary fates differ strikingly among lineages. In mammals and birds, highly degenerated Y/W chromosomes have remained s...

Plastic Germination, Temporal Niche Partitioning and Emergent Assortative Mating in Annual Plants Temporal environmental fluctuations can drive genetic diversity and species coexistence via the storage effect. Using eco-evolutionary models of annual plants, we show that adaptive plasticity in see...

V happy to share new paper led by @schmidmax.bsky.social: doi.org/10.1111/ele....

We show that plastic germination timing not only buffers environmental fluctuations (storage effect) but also promotes divergence, temporal assortative mating and thus ecological speciation. Thx @dee-unil.bsky.social

Evolutionary causes and consequences of gene duplication Nature Reviews Genetics, Published online: 16 February 2026; doi:10.1038/s41576-026-00935-5Gene duplication is a key evolutionary mechanism, as initially redundant paralogues diverge over time. The authors review how adaptive and non-adaptive forces influence the evolutionary fates of gene duplicates, highlighting the importance of function–fitness relationships and gene expression dynamics.

Eusociality has independently evolved in multiple arthropod lineages

Eusociality has independently evolved in multiple arthropod lineages

Comparative analysis across 5,678 insect species shows that, when you control for phylogenetic bias, eusociality has not evolved at a faster rate in haplodiploid species. www.pnas.org/doi/10.1073/...

A small polymerase ribozyme that can synthesize itself and its complementary strand The emergence of a chemical system capable of self-replication and evolution is a critical event in the origin of life. RNA polymerase ribozymes can replicate RNA, but their large size and structural ...

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?

Excited to share our latest work in @science.org on a new small polymerase.

"Nothing could be less inviting than the first appearance. A broken field of black basaltic lava, thrown into the most rugged waves, and crossed by great fissures, is everywhere covered by stunted, sun-burnt brushwood, which shows little signs of life. The dry and parched surface, being heated by the noon-day sun, gave to the air a close and sultry feeling, like that from a stove: we fancied even that the bushes smelt unpleasantly. Although I diligently tried to collect as many plants as possible, I succeeded in getting very few; and such wretched-looking little weeds would have better become an arctic than an equatorial Flora."

Just passed my #Dutch #B1.4 exam and honestly… this might be my greatest academic achievement since my tenure-track 😅🤣

Can explain #sexchromosome #evolution in 3 languages (sort of), but ordering a broodje kaas without panicking? That’s the real milestone 🇳🇱📚

Time to publish responsibly: DAFNEE, a database of academia-friendly journals in ecology and evolutionary biology Abstract. The current economics of scientific publishing reveal a profound imbalance: academia pays prices far exceeding the actual costs of publication. R

Responsible publication of your research!

To help you do this @nicolasgaltier.bsky.social and coauthors have put together a handy database of academia-friendly journals, DAFNEE. You can read about it in their article recently published in @jevbio.bsky.social:
