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

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.
Really excited to have the new issue of Paleobiology @paleosoc.bsky.social out celebrating the 50th anniversary of #punctuatedequilibria #macroevolution #paleobiology #palaeontology #paleontology @nilese.bsky.social www.cambridge.org/core/journal...

Wow—thanks @bruceslieberman.bsky.social for posting the entire issue of Paleobiology vol 51/4 2025 “Punctuated Equilibria at 50”—open access papers from the GSA 2022 50th anniversary symposium! A great community celebration!!

"Speciation and extinction are invoked in all predictions for paleontological patterns. What processes one chooses is less important than that the meanings are clearly stated. Thus, I introduce my arguments with reference to the phylogenetic trees in figure 1 (Vrba, 1993)".

I think this paper will be a tipping point in understanding the fundamental importance of punctuational change in all “evolutionary” domains—i.e. where evolution is seen as the fate of transmissible information
Sergi Valverde@svalver.bsky.social · last yr.Douglas et al. shows that up to 99% of evolutionary change occur at branching points across genes, morphology, and language. A major step for punctuated evolution, aligning with our goal of a unified framework. @nilese.bsky.social @andrejpaleo.bsky.social #EvoBio #CultEvo doi.org/10.1098/rspb...

Great to see Ilya Tëmkin’s recent thinking on Hierarchy Theory—and on the newly reconstituted “Bretskyan Hierarchy.” Towards a “General Theory of Biology” indeed!
