Why do endotherms spend so much energy? Juan G. Rubalcaba describes a theoretical model that shows that species followed one of two possible evolutionary patches: live fast while spending a lot, or live slowly and keep your costs low. Read now!

These two strategies likely produced bifurcations and abrupt evolutuionary transitions to endothermy. I speculate that declining temperatures n the mid Triassic triggered endothermy in early mammal and avian lineages

When the costs and benefits of high body temperatures are combined, two strategies emerge: 1) save energy and be an ecotherm OR 2) spend as much as you need as an endotherm

I used a theoretical, energy-balance model to explore how and why an energetically expensive trait such as endothermy evolved multiple times among both plants and animals

Author-Paid PublicationFees Corrupt Science and Should Be Abandoned Thomas J. H Morgan & Paul E. Smaldino

As grant money starts drying up, it's more important than ever not to waste it on paying publishers' open access "article processing fees" when we can host PDFs for free. Tom Morgan and I wrote a paper on this, forthcoming at Science and Public Policy. Accepted draft here: osf.io/preprints/os...

Se ha filtrado el borrador de ley de universidades que está preparando la CAM. Si se aprueba, será la muerte de la universidad pública madrileña. Es escandaloso. No exagero. Se vienen tiempos oscuros como no espabilemos. Explico algunos puntos críticos. Va hilo. 👇

Real breakthroughs come from long-term investment in public research and then exploited by big tech companies
