🧵🪸📖 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” #evolution
Juan L. Cantalapiedra@singerstone6 May 2022
📖 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. #evolution #paleobiology #Darwin #darwinism

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! @PalaeoPhilo doi.org/10.1093/jeb/voag105

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. nature.com/articles/s41467-0…
