Starting #ESEB2025 a bit late, with an exciting symposium on whole genome duplication. They couldn’t fit all of the talks in, I’ll be talking on “Gene expression variability and evolutionary outcomes after whole-genome duplication in fishes” tomorrow in the Genetics symposium. #GeneDuplication #GenomeDuplication #MolecularEvolution

We posted this cool preprint between Xmas and new year, now time for a thread about the results: Begum et al "Phylogenetic modeling provides evidence for sudden shifts in expression after small-scale duplication in vertebrates and strong support for the ortholog conjecture"

Interesting preprint dating whole genome duplications in vertebrate evolution relative to hagfishes, which I had missed this Spring:
• 1 genome duplication before, 1 after hagfish divergence, +2 at the basis on cyclostomes
• nice investigation of relation between genome duplication and morphological diversification (not much).

Amazing seminar @dee_unil today by Magdalena Bohutínská (MajdaHolcova on Twitter). A researcher and a research program to follow! #ConvergentEvolution #MolecularEvolution #GenomeDuplication #PlantEvolution
