La colonisation de la terre ferme par les plantes aquatiques a eu lieu il y a environ 500 Ma, un processus qui s'est étalé sur 30 Ma (temps nécessaire pour que les mécanismes adaptatifs adéquats se mettent en place). Comment les scientifiques retracent-ils l'histoire de cette terrestrialisation ? 👇

Last week, I attended the EMBO workshop in Vienna on early land plants and terrestrialisation.
There, I presented my research on rhacophytalean evolution, focusing on a reappraisal of the genus Cephalopteris from the latest Famennian of Bjørnøya. 🌿🌿

The "horseshe crabs nested deeply within Arachnida" is my personal enemy. There's just no way. You see, horseshoe crabs are wet.
Look it would be so fucking good. And i know we know very little about the history of arachnid terrestrialisation. But there's just no way. They're wet.

How did animals repeatedly conquer land? 🌊➡️⛰️ We analysed ~1,000 gene repertoires (24M genes!) from all animal phyla to uncover how this happened. Work led by @gemmaeling.bsky.social & Klara Eleftheriadi, both first coauthors of this titanic effort!

had a key role in enabling terrestrialisation. To be honest we haven't given the question much thought, precisely because of the lack of data.
The paper should not have been published, not in this form. It does a disservice to the field. I'm very, very unhappy about this.

Convergent genome evolution shaped the emergence of terrestrial animals - Nature
Comparisons of 154 genomes from 21 animal phyla and outgroups have been used to reconstruct ancestral adaptation to life on land across 11 distinct terrestrialization events, revealing strong evidence for convergent genomic evolution across the animal kingdom and recurring periods of terrestrial colonization.

Hints that mammalian loss of ancestral green/blue cones due to rapid terrestrialisation, not nocturnalisation?
