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...

If universities anywhere are hiring an Evolutionary Biologist/Paleontologist please let me know! I'm on the market for Tenure Track positions!!

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

Macroevolutionary role reversals in the earliest radiation of bony fishes
Troyer et al. examine lower jaw evolution in Silurian-Devonian bony fishes and find
substantial differences in patterns of morphological disparity, rates of shape evolution,
and functional diversity b...

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
