A juvenile pipefish. I believe the long filaments probably mimic siphonophores, but I'm no expert on this stuff. Pic from Balayan Bay, Anilao

An episodic burst of massive genomic rearrangements and the origin of non-marine annelids 🧪

Suggests genomic landscape of Clitellata resulted from a rare burst of genomic changes that ended a long period of stability that persists across large phylogenetic distances.

If you're new to demographic history inference from population genomics, try this webapp I created to illustrate how dadi fits bottleneck models to site frequency spectra: ryangutenkunst-dadi-two-epoch.hf.space . It even outputs files for submitting to the GHIST competition! ghi.st

To test whether alternative splicing contributes to adaptation, Rodríguez-Ramírez & Peichel analyzed gill RNA-seq data from marine and freshwater sticklebacks, and identified differentially spliced genes enriched in regions under divergent selection.

Maybe I'm too much of a negativist, but I've always disliked the 'de-extinction' field. It all looks like one big grift that attracts charlatans and pretenders, and which is forever making false claims and promises that distract people from what's actually interesting about extinct animals.

Aquatic crustaceans of MANY types are fossilized in amber from 23 mya Mexico, but amber comes from tree sap - how did crustaceans get there??? We think the fossils may come from estuarine mangroves. Shown here are ostracods, copepods, isopods, and even CRAB.
