Excellent talk on #evodevo of mesoderm compartments in #chordates by @hector-escriva.bsky.social here @univie.ac.at! #Zoology #Development

Timeline cleanse from our front yard this morning.

We then studied the expression of these paralogs in a variety of #chordates: FoxQ2a is found in the amphioxus anterior ectoderm and in retina photoreceptors of zebrafish and chick 👁️ The real surprise was the mysterious FoxQ2c, which we found expressed in the endoderm of amphioxus, lamprey and skate!

Support for the deuterostome clade comes from systematic errors There is a long-standing consensus that the animal phyla closest to our own phylum of Chordata are the Echinodermata and Hemichordata. These three phyla constitute the major clade of Deuterostomia. Re...

What was our common ancestor?! Mitigating sources of error @maxjtelford.bsky.social @anaserrasilva.bsky.social & colleagues cannot distinguish between monophyletic & paraphyletic Deuterostomia (#hemichordes, #echinoderms, #chordates).

Taxa with available #chromosome-level genomes, other genomes, and no genomes, for #chordates, #arthropods, #plants, and #fungi based on NCBI #taxonomy and @enasequence.bsky.social #data

To better understand the impact of #GeneLoss on the #evolution of mechanisms #development, during the PhD project of @gasparsanchez.bsky.social we investigated the #Fgf system on #appendicularian #tunicates, the sister group of vertebrates, in the context of our own phylum, the #chordates.

YES physics was super easy! #superhappy. Now to study for Lab exam 3 for tomorrow #chordates
