Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolutionNew World vultures are the only avian clade proposed to lack a syrinx and have been described as non-vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel ...onlinelibrary.wiley.com
Our paper (also, my first first-author paper) is now available in MEE early view! In this study, we introduced a state-dependent Ornstein-Uhlenbeck model we implemented in RevBayes to test adaptive hypotheses in macroevolution. (1/3) besjournals.onlinelibrary.wiley.com/doi/10.1111/...
An efficient Bayesian phylogenetic approach for joint inference of continuous and discrete trait evolution under a state‐dependent Ornstein–Uhlenbeck modelMacroevolutionary adaptation of a continuous trait to different discrete states across species can be modelled using a phylogenetic state-dependent Ornstein–Uhlenbeck (OU) process. Existing infere...besjournals.onlinelibrary.wiley.com
Everything is coming together for the Friends of UMMP BBQ this weekend. I have 24 pounds of pork shoulder marinating. It goes on the smoker tomorrow morning for about 12 hours. And, I picked up these amazing chocolate sprinerle trilobite cookies from my dear friend!
Exhilarated to share a 2nd @science.org cover article this month from our lab @ucberkeleyofficial.bsky.social! A collaboration with US & Mexico colleagues on the role of a Mexican biogeographic holding pen in shaping the Great American Biotic Interchange (GABI)(1/11) www.science.org/doi/10.1126/...
Here is @ucberkeleyofficial.bsky.social Bob Sanders' write-up of our Great American Biotic Interchange work: news.berkeley.edu/2026/07/30/n...
North and South America weren’t always connected, but their mammals still found a way to intermingle - Berkeley NewsBefore the Panamanian land bridge formed about 3 million years ago, mammals on the two continents were isolated — or so biologists thought. New fossils show that they found ways to mix long before tha...news.berkeley.edu

I am recruiting Ph.D. students this cycle. Students interested in deep-sea fishes and phylogenetic comparative methods are an especially good fit.
🧵1/6 New paper from #NearLab dropped! Wood et al. (2026) tackle a long-standing mystery: how did freshwater perches, walleyes, and darters (Percidae) end up on BOTH sides of the Atlantic? Spoiler: they may have swum there. 🐟🌊 #Ichthyology #Evolution #Systematics

Today is my first day in office as the new curator of vertebrate paleontology at @nhmdk.bsky.social & @ucph.bsky.social! 🇩🇰 🏛️ 🦴 🦕 😁 Starting off right with some proper Paleozoic Greenlandic friends (🐟/🐸, 🦈) and an extremely Danish office surprise! 🧱
Out on the RV Tom Crean and had a bit of a landmark day. Technically not my first angler, but this extraordinary, beautiful animal made me genuinely emotional. It’s an absolute privilege to get to meet these animals that I’ve adored for so long! (She’s a triplewart seadevil, Cryptopsaras couesii)

Stoked to see our paper out as a pre-print! Check it out if you're interested in how we can expand comparative methods to better accommodate the many-to-one mapping of evolutionary process to pattern... (or if you think frogs are cool) @gjslater.bsky.social www.biorxiv.org/content/10.6...

Proud to share our latest paper in out in Nature today on the origin of #snakes. We present Tametara mirim, an articulated 3D preserved stem snake from the Late Cretaceous of Brazil. Tametara helped us re-tell the story of snake origins in a novel way... www.nature.com/articles/s41...
