Another new paper out now: led by Amy Betz from the @bruceslieberman.bsky.social lab on how a variety functional traits did or didn't impact extinction risk in the Plio-Pleistocene-Recent western Atlantic regional mass extinction Of the 16 traits considered, none was correlated with increased risk

Happy to share paper in #Palaeontology led by my former @ku-eeb.bsky.social grad student Amy Betz w/ @jonhendricks.bsky.social @fossilsndcoffee.bsky.social and Portell & Strotz on factors impacting #extinctions in #marine #mollusks. #paleontology onlinelibrary.wiley.com/doi/epdf/10....

Finished my first book of 2026, Macroevolutionaries by @bruceslieberman.bsky.social and @nilese.bsky.social. It’s a wonderful tribute to Gould, every essay is enlightening, but the one on Kestrels is my favorite.

Big 🙏 to Tricia Kelley of UNCW for her review of my & @nilese.bsky.social 's @columbiaup.bsky.social 📕 book "Macroevolutionaries" in @ncse.bsky.social reports: ncse.ngo/review-macro... #macroevolution #paleontology #palaeontology #punctuatedequilibria #stephenjaygould

Yes, some people's legacies are complicated. For example, Watson. After all, though he was racist, don't forget his other traits. For example, he was also sexist. And also anti-semitic. And a data / idea thief. So let's not forget all the different facets.

Excellent write up by @geosociety.bsky.social describing grant funded research by former post-doc Claudia Nunez-Penichet now @vt-invasivespecies.bsky.social on impending #marine #extinction threat www.geosociety.org/GSA/News/pr/... @kubiology.bsky.social @researchatku.bsky.social @kunhm.bsky.social

Hendricks and @bruceslieberman.bsky.social discussed the vital importance of museum collections for studying macroevolution in an article for the Paleobiology special issue celebrating the 50th anniversary of Punctuated Equilibria www.cambridge.org/core/journal...

Interesting a lot of recent theory-focused papers I've been reading about fossils don't acknowledge the vast amount of paleobiological literature on the subject(s) they're discussing. I'm happy folks are excited about fossils but also confused why folks seemingly aren't reading papers about fossils

New paper! The 1st publication from our NSF grant investigating local to global biodiversity patterns in marine invertebrates across the O-S boundary is out! Here, we describe a new crinoid from Anticosti Island & use Bayesian tip-dating approaches to quantify uncertainty in its stratigraphic age 🧪

For perspective, last year, 1.2 million unique visitors used our online educational materials...it's really a need of only 1 or 2 dollars per user, and it won't be an annual ask. Just one make or break 6 month period for an almost 100 year old research institution

New day, new paper! 🦣🌍 Led by @mapaslab.bsky.social ab.bsky.social PhD student Sofía Galván and out now in Global Ecology and Biogeography in which we asked: "Could future palaeontologists detect today’s biodiversity patterns from fossils alone?" 🔗 onlinelibrary.wiley.com/doi/10.1111/...

For hundreds of millions of years, marine annelids had remarkably stable genomes. Then, a sudden and drastic transformation occurred. In non-marine lineages like earthworms and leeches, the genome structure massively reorganized in a short evolutionary window.

A new paper in Nature Ecol & Evol by @rosafernandez.bsky.social et al. shows a #punctuated burst of genome evolution in #annelids as they transitioned from marine to land and freshwater habitats.

Can the structure of knowledge evolve like life itself? In our new MBE paper, we show that the Gene Ontology evolves through mechanisms shared with cultural and technological systems—reuse, modularity, and curator-driven restructuring. Here’s what we found: 🧵
