"Useless" and/or "silly" federally-funded research has turned the United States into the world’s leader in science and technology over the past 75 years. Such science is under attack throughout the federally-funded agencies in the United States. More at: www.americanscientist.org/article/%E2%...

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

Another pre-print led by @wrad07.bsky.social 🐟🧬 We generated a reference genome for Hypostomus & used whole genome re-sequencing to ID invasive suckermouth catfish species in TX. We also investigated genetic sex determination to assess feasibility of genetic biocontrol via YY supermale approaches.

First pop gen paper from our lab! We find repeated evolutionary turn over of sex chromosomes in darters contributes to reproductive isolation. Turnover may be an escape hatch to resolve mitonuclear conflict & neo sex chromosomes evolved via a rare recessive mutation. www.biorxiv.org/content/10.1...

Why do speciation rates vary across the tree of life? Some of the best yet most underappreciated places for this investigation are natural hybrid zones. This preprint takes you to the hybrid zones in the origin of species to find a clue. 👉 shorturl.at/N7FXE #Speciation #Evolution #hybridization

Why do males and females often differ in traits? The expected answer: selection. But our new paper in GENETICS shows that genetic drift alone can generate sexual dimorphism — even when male & female optima are the same

Great to see this paper out I contributed to:

Extremely grateful to have presented the first half of my first project on darter sex chromosomes at #Evol2025 - stay tuned for the preprint coming soon!!

Very exciting to present this idea at #Evol2025. The toxins and pigments of aposematic animals often act against infections, providing animals with individual fitness benefits.

Genome size is surprisingly variable even WITHIN species. Dunja Lamatsch, Martin Haase, Maria Pilcher, and I use flow cytometry to show a nice example of this variation in this new paper, perhaps connected to a resolving whole-genome duplication, in our snails. 💜🐌🧬 doi.org/10.1098/rsos...

I’ve been studying gene regulation in primates for over 20 years, and using RNA-seq since 2008 to compare expression across species. We thought we were being careful. We used curated orthologous exons to minimize alignment bias and focused on biologically meaningful comparisons. We were wrong.

Unsolicited listicle: My list of the most criminally underused/underappreciated phylogenetic comparative methods. Note, I am not involved in ANY of these methods; but I see them as things people are often asking of comparative data but have been surprised at how infrequently they have been cited.

"Women are PIs on 58% of the canceled grants, although they are PIs on only 34% of all active NSF grants. Similarly, Blacks are PIs on 17% of the terminated grants, although they make only 4% of the total pool. Hispanic PIs and those with disabilities were twice as likely to lose a grant."
