Out now in Biology Letters, my latest paper tackles an apparently simple question: how many characters are needed to reconstruct a phylogeny? TL;DR: in most cases between 100 and 500, more than a substantial portion of morphological datasets, but the story is more complex... doi.org/10.1098/rsbl...

Do you like cichlids? Fossils? Fossil cichlids? Would you like to study them as part of a graduate degree at the University of Michigan, joining an NSF-funded project? Get in touch.

Excited to announce that the 1st paper from my postdoc is now out in @currentbiology.bsky.social ! Using a large dataset of 3D preserved fossils, we explore the diversification of jaws in early bony fishes. 1/15

This is the most relevant article to NIH and research cuts I’ve seen.

Imagine if this was today , how many people would be saying “Why are we studying Gila Monsters and their impact on diabetes ? That’s wasted money !”

Well the award for most cowardly, boot-lickingest academic society has squarely gone to the American Society of Microbiology, who has taken down features of various non-white scientists. Absolutely pathetic behavior. Those articles are now coming up as “under review”. Truly sickening cowardice here.

Here's a starter pack for early career researchers in evolutionary biology. I prioritized the most-junior folks, and this list quickly filled up with undergrads, grad students, and postdocs. Might do another list later, but I'm tired. Have fun everyone! 🐒 #evobio
