Our work on chromatin evolution in brown algae is now published in @natecoevo.nature.com! We show that developmentally complex brown algae evolved without epigenetic silencing pathways long thought universal, underscoring why non-model lineages are important to study. www.nature.com/articles/s41...

From ancient catalytic folds to retrotransposons and retroviruses

Most creatures use daylight to keep time. But a newly discovered jellyfish species has a mysterious biological clock that tracks periods of 20 hours, instead of 24. It suggests there may be more unconventional clocks across the tree of life.

Delighted to see our work on the cover of Systematic Biology!! We introduce an approach for analyzing pairwise-defined traits (e.g. 'strength of RI', 'diet niche overlap') in a phylogenetically informed context (R package 'phylopairs' now on CRAN). Read it here: academic.oup.com/sysbio/artic...

This is kinda bonkers. In addition, 20 amino acids were found on Ryugu, along with uracil and vitamin B3. These have been found in other instances, but since the samples from Ryugu were collected directly from the asteroid and delivered in sealed capsules, contamination on Earth could be ruled out.

Do you prefer the mountain 🏔️ or the beach 🏖️? The Mazarine blue chose both.

Before 1990 Brimstones (G rhamni, citroenvlinder) would be more abundant in summer than in spring, but this has shifted over time. The only explanation I can think of is that they go into hibernation sooner after appearing in summer, maybe to avoid summer heat. Other ideas welcome. #vlindermaand

In Eudaminae skippers, wing tails and iridescence have evolved many times and are linked to faster diversification — yet these traits are also often lost, revealing a very dynamic, environment-driven butterfly wing evolution. 🦋 doi.org/10.64898/202...
