We need to take a moment to salute Gianni Infantino for being the first person in history to get 55 European countries to unanimously agree on anything.

More on rate-scaling in phenotypic evolution, pointing toward biological explanations, from Brune Kinneberg & Voje. Lots of debate about this pattern, but comes down to how we define "noise" vs. "biology" as represented in models. Important philosophical discussion. academic.oup.com/evolut/advan...

Rate-time scaling in phenotypic evolution: Limitations of current models in capturing temporal dynamics

Abstract. Evolutionary rates correlate negatively with time, which makes it complicated to compare rates across lineages that have diversified on different

Is it possible to estimate rates of phenotypic evolution that are independent of the time interval covered by the data? In theory, yes — even when the data are incomplete and biased. But in practice? Not so much. Amazing work by @vildebruhn.bsky.social

Looking for a PhD opportunity? I'm hoping to recruit someone to my group at Durham University to work on a project combining fieldwork and labwork to study speciation in rubyspot damselflies: iapetus.ac.uk/studentships... Get in touch if you want to chat!

Tree evolution is surprisingly quirky! 🌳 Trees are likely ancestral in many plant groups, often re-evolve on islands, and Arabidopsis can be made tree-like by tweaking a few genes. We revisited what genes really make a tree a tree using comparative genomics. @trhvidsten.bsky.social #trees #evolution

Excited to share our new paper where we find that the rise, decline and fall of clades is not explained by the usual suspects (diversity-dependence, ecological opportunities) but rather by species' insidious loss of macroevolutionary fitness: www.nature.com/articles/s41... 1/3

Loss of macroevolutionary species fitness explains the rise and fall of clades - Nature Ecology & Evolution

The interplay between speciation and extinction rates shapes clade diversity dynamics. Using a novel phylogenetic model that includes living and fossil lineages, the authors estimate speciation and ex...
