Model showing language diversification associated with population growth during the expansion of agriculture in the Age of Empires, and language diversity decline with European colonization
Three models of himan language diversification. Megadiverse paleolithic (yellow), demographic boost with sorad of agriculture (green), and premodern equilibrium (blue).

The most exquisite CT scan I've seen - by @Ella_Nicklin w/ @FloridaMuseum. The entire body of a hatchling Californian Horn Shark (Heterodontus francisci); showing the early coverage of skin teeth of different shape and size, with very prominent fin spines (aka the horns)!🦈

A great week for e-fish papers. In this one Poon & Crampton show that electric eels predators suppress their low-voltage electrolocation EODs when hunting weakly electric gymnotiform prey which in turn suppress theirs to hide from the eels. Cool stuff! doi.org/10.1016/j.cub.2026.0…

❤️ Blind gobies (Typhlogobius californiensis) are finding love in an intertidal place. ❤️ Researchers with the @FishEvoLabSIO study how these fish have evolved unique adaptations that provide insight into evolution, biodiversity and more. ⤵️

❤️ Valentine’s from the intertidal zone:
Blind gobies (Typhlogobius californiensis) form long-term pair bonds, and we study their evolution through genomics and field research. Interested in supporting our work? Watch the video and help share our research

🐠 📈Researchers with @FishEvoLabSIO dive into how ancient ocean temperatures shaped the evolution of fish body size, focusing on the wonderfully weird world of tetraodontiform fishes. Dive into this video to learn more! ⬇️

Back in October 2023, @Scripps_Ocean Professor @anelachoy invited me on a research cruise hundreds of miles off California to study open ocean Goodwin’s. I helped ID deep-sea fishes collected via a MOCNESS net system (opening–closing trawl with known capture depths)

🐠 Thanks to @NSF support & a partnership between @uprm and Scripps Oceanography, thousands of marine specimens were saved, conserved & integrated into a world-class research collection, fueling discoveries in evolution, biogeography & conservation. 🔬

Behind every specimen there’s a story, and sometimes a rescue mission.

🐠 Tiny but mighty! New research on goby fishes, supported by Scripps Oceanography scientists, reveals how some of the smallest vertebrates on Earth control their body size at the genetic level, offering clues to the incredible diversity of life on Earth. pnas.org/doi/10.1073/pnas.25…

🐟 Not all fish are cold-blooded! Tunas, marlins, opahs, and butterfly kingfish rewrote the rulebook with warm-bloodedness. New research from @FishEvoLabSIO explores how ecological interactions + evolutionary innovation reshaped life in the ocean. 🌊

Ever wondered how #sharks produce an unlimited supply of teeth? Our new preprint uncovers the genes within the dental stem cell niche driving lifelong tooth development. "Shark tooth regeneration: RNAseq reveals genes for unlimited dental renewal" 🦈🦷

🌅 We love a good #Scrippshenge timelapse 😍
@UCSanDiego photographer @ErikJepsen was recently on the scene to capture the glorious event where the sunset aligns perfectly with #ScrippsPier. If you can't catch it tonight, try again in May 2026!

Excited to share our new paper in Science Advances! We investigated the evolution of endothermy in ray-finned fishes by integrating phylogenomics, ecomorphology, fossil occurrence, and comparative genomics across 205 marine vertebrates.
