Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

New preprint: 338 coleopteran genomes reveal exceptional rearrangement variation compared to other insect orders. Big congrats to @arf-mln.bsky.social, for getting this giant piece together. Big collaboration of @joanameier.bsky.social's and my groups. 🧵👇 doi.org/10.64898/202...

International students could once stay as long as they needed to complete their college degrees, but that's changing, and the restrictions could cut into college budgets. n.pr/4fu5bny

New study reveals 2D morphometrics captures major patterns of fish body shape variation but can underestimate subtle 3D features. For broad comparative studies, 2D is often sufficient; for fine-scale morphology, 3D remains essential Torgersen et al anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

Happy to share this 'capstone' project from my time as a postdoc @umich.edu, where we show that hierarchically nested bursts of body-shape evolution may underlie much of perching-bird diversification over ~50 million years. Free access link here: rdcu.be/fuxB1

The lab and I are halfway through our final data collection trip to the Smithsonian fish collections. So far we have measured 1236 specimens from 483 species in 75 families. Here is one of my favourite so far, a Galapagos four-eyed blenny (Dialommus fuscus) which is amphibious.

For #FossilFriday, and in honor of Dr. Sanaa El-Sayed, a beautiful 62-million-year-old veliferid from Egypt alongside the living sailfin velifer (Velifer hypselopterus).
