1/ A brief thread to one of the most useful metaphors in evolutionary biology [Galton’s polyhedron] using quotes from chapter 5 of Gould’s “The Structure of Evolutionary Theory”

📖 Currently reading Gould’s extensive revision ‘The Structure of #Evolutionary #Theory’ 🪸, a massive #book packed with interesting reflections. I will be tweeting quotes from it in this 🧵, both from him and others cited therein.

That's how large-bodied mammals declined through the late Cenozoic. Slow attrition of origination rates when extinction rates stayed the same. “The Entwives effect”.

Slaughtering Fin Whales is barbaric and has no place in 21st Century. #Iceland continues to ignore global opinion. Please sign petition. Could Fin #Whales migrating through Celtic Sea off Wales and Ireland get harpooned?!!

A new study by @AndriiRozhok @niles_eldredge and James DeGregori which presents a novel population genetic mechanism of evolution—the directional selection (of deviating forms) also selects, as a dynamic spandrel, higher mutation rate forms!

I am looking for graduate students to join my lab in Fall 2027. If your interests lie within the realms of phylogenetics, macroevolution, and/or invertebrate biodiversity please reach out to me!!

"We find three macroevolutionary transitions in mammal assemblages... regional Asianmid-Eocene aridification and...global events — the Paleocene-Eocene Thermal Maximum (...extreme warming 56Ma) and the Eocene-Oligocene Transition (prolonged cooling 34Ma)."

The Ice Age woolly rhinoceros may have owed much of its evolutionary success not to the frozen Siberian landscapes with which it is most closely associated, but to the more temperate regions of Eurasia, a sweeping new analysis of ancient DNA and Pleistocene habitats suggests.

Durante los últimos 7 millones de años, la diversidad de los megaherbívoros en África se desplomó. Los últimos modelos apuntan a que se devió no a una mayor tasa de extinción respecto a otros mamíferos sino a una lenta tasa de especiación.

La baja densidad poblacional y las enormes extensiones de territorio que necesitan los megaherbívoros (🐘, 🦏, 🦛, 🦒) reducen su especiación
