Excited to see this story out as a preprint ✨

Eponges ou cténophores ? Duel au plus profond du vivant pour le titre de premier animal La controverse secoue les spécialistes de l’arbre de la vie. Deux camps s’affrontent, avec chacun sa lignée marine favorite. D’un côté, la créature la plus sommaire du règne animal ; de l’autre, des p...

Sponges, ctenophores, and the statistical significance of syntenies Abstract. Shared fusions between ancestral chromosomal linkage groups have previously been used to support phylogenetic groupings, notably sponges with cni

@rcply.bsky.social argues that phylogenetic inferences in sponge–ctenophore–bilaterian relationships based on shared chromosomal rearrangements suffer from insufficient statistical support.

Most papers are arcane studies in niche areas read by experts who ought to be able to understand them (and science managed without peer review before the 1960s). But they need to be able to trust the data, and ‘peer reviewers’ can’t tell them if it’s real.. 2/2

"Our tissue-level atlas reveals ectodermal & endodermal cell types in larvae & adults occupy distinct transcriptional spaces"

Evolutionarily conserved transcriptional regulators control monoaminergic neuron development To what extent conserved developmental programs specify homologous cell types is a central question in biology. Here, we address this by focusing on reconstructing monoaminergic neuron development in ...

New preprint out! Evolutionarily conserved transcriptional regulators control monoaminergic neuron development.
We uncover how ancient regulatory programs orchestrate the neurons that produce serotonin and dopamine across 550 million years of evolution.

Excited to share our new work on the 3D architecture of the ctenophore aboral organ!

We explored its remarkable cellular diversity and integration with the syncytial nerve net, uncovering connectivity and insights into the evolution of sensory complexes.
