Is evolution predictable? Would the biosphere look the same if we re-played the tape of evolution, as conjectured by SJ Gould? Here's an excellent paper on this challenging problem by Michael Lässig, Ville Mustonen and Aleksandra M. Walczak www.phys.ens.psl.eu/~awalczak/PU...

Missing data and the problem of handling variable-incomplete datasets is a common feature of ecological, evolutionary, biogeographical and palaeontological analyses. Here is a refreshing review arguing for the application of a generalized "Multiple Imputation" Rubin (1976) procedure 👇

Remember folks: the abundance of terrestrial animals weighing over a ton was normal for a few hundred million years. It's the modern world that's the anomaly. I made a whole video about this topic, of which I'm particularly proud of youtu.be/lf-H7YvA7YY

For #valentinesday and #FossilFriday, here's Tyrannosaurus engaging in face biting, a behaviour evidenced from numerous tooth gouges and puncture wounds in their skulls. Among living species, face biting is strongly correlated with the onset of sexual maturity, so this image is love-adjacent, sorta.

Orbitally oscillating ice ages are not a Neogene inversion; we had them before. Last time was in the Late Paleozoic. Expansion of terrestrial floras & intensified weathering got it going. But we're not sure why it ended. One option is a shift in the CO2 sinks.🧪⚒️ www.sciencedirect.com/science/arti...

This is how fascism operates. In the 1930s the Nazi regime enforced strict control over academic institutions, censoring research and silencing dissenting voices. Many left Germany: Einstein, Born, Hahn, Meitner, Schrödinger, Szilard etc. etc. Today, US scientists are looking at moving abroad.
