Interested in how species diversity is split between major animal groups? Here is the infographic for you! 🧪⚒️🦀🦑 #evosky
An infographic showing the number of described and estimated species for major animal groups. There are more insects than anything else. Of the remaining groups, arachnids and nematodes are the most diverse.

It'll be pretty embarrassing if the dinosaurs went out with more dignity than us. They can't say they knew about the meteor for decades, knew exactly what to do about it, had all the technology and resources to stop it but didn't so five of them could own everything

A fully updated preprint is now live on @biorxivpreprint.bsky.social :) “Look and see” was a rather important line of thinking regarding freshwater sponge-microbe interactions, centering on the importance of spatial dynamics when evaluating animal microbiomes 🧽🦠🧪 www.biorxiv.org/content/10.6...
Graphical abstract depicting a proposed model of microbial colonization of the skeletal matrix of the freshwater sponge, E. muelleri, during periods of dormancy. This graphic highlights that an epithelium physically separates the host mesohyl from the microbial communities residing within this host-derived external matrix.

Transgenic means that genes from 1 organism have been put into another. We make transgenic mice to understand how genes influence biological processes. We make transgenic plants to make them more nutrient rich. We make transgenic bacteria so they make medicine for us. It's wide-ranging & v. useful.
