It's finally here! Great start of the summer. We got our latest preprint from @chemamd.bsky.social in @qmulsbbs.bsky.social @qmulse.bsky.social, showing evidence of developmental system drift in the specification of dorsoventral (belly vs back) axis in annelids 🪱🪱🪱

3 different flavours of Polychaeta (bristle worms) in one friendship group! The biggest is from the family Spionidae, the orange one was featured is yesterday’s post, from the family Serpulidae, and the littlest is a mystery to me!

Drawing together findings from several projects over many years, we make a case that neural cell types in the Clytia larva have two embryological origins: i-cells and ectodermal.

Out today, our take on 6-methyladenine #6mA evolution in Eukaryotes @natgenet.nature.com. We asked a simple question, is really DNA 6mA common across the eukaryotes? The answer is "yes" if you're a unicellular eukaryote 🦠, not so if you're multicellular 🐝🌱🍄. www.nature.com/articles/s41... 1/9
Adenine DNA methylation associated with transcriptionally permissive chromatin is widespread across eukaryotes - Nature Genetics
Long-read sequencing in 18 unicellular eukaryotes reveals that 6mA is widespread across eukaryotes and is enriched at transcriptionally permissive regions, which are also marked by H3K4me3.

Ectopic head regeneration after nervous system ablation in a sea anemone
Via genetic ablation of neurons, Mazloumi Gavgani et al. show that the nervous system
is essential for defining axial polarity during whole-body regeneration in the sea

Glad to see our phoronid genome study featured on the cover of @currentbiology.bsky.social! It shows how genome structure can be used to test competing hypotheses of nested topology and how derived structural changes provide evidence for monophyly.

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.
