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...

Neo-liberalism has killed off imagination and creativity.
"In politics it used to be actually possible to think big. To think about things like: the U.N, space programmes, the welfare state and so on. Nowadays, no Govts are thinking on anything like that scale and seem to be completely incapable of doing so. Statesmen seem to have given up on the idea that they can create anything fundamentally new or bold." . - David Graeber

I’m sorry, but it is disgraceful to be an academic who uses this technology to conduct research. It should be prohibited in all of our scholarly institutions, including universities and journals.

A fourth child has frozen to death in Gaza in just 10 days—two of them babies—as Israel continues blocking tents and winter shelter aid, despite UN supplies pre-positioned at the border that could immediately shelter more than 1.3 million displaced Palestinians.

This is fucking grim. Somebody invented a white guy, an "IT professional" named Edward Crabtree, who stopped the Bondi shooting and spread it all over the internet, which was picked up by AI agents and slop aggregation sites.

The real hero is a fruit stand owner named Ahmed el Ahmed.
A wrong Grok post making up a white guy who stopped the Australian mass shooting. BBC 'Hero' who wrestled gun from Bondi shooter named as Ahmed al Ahmed Emily Atkinson Sun, December 14, 2025 at 1:06 p.m. CST 2 min read A "hero" bystander who was filmed wrestling a gun from one of the Bondi Beach attackers has been named as 43-year-old Ahmed al Ahmed. Video verified by the BBC showed Mr Ahmed run at the gunman and seize his weapon, before turning the gun round on him, forcing his retreat. Mr Ahmed, a fruit shop owner and father of two, remains in hospital, where he has undergone surgery for bullet wounds to his arm and hand, his family told 7News Australia.

In a sane world, the government guilty of committing genocide would be dismantled, and forced to pay reparations. Instead they are allowed to corral their victims into a concentration camp and steal their land. We live in the most obscene of all possible timelines.

Because in China, industrial policy means investment can be directed toward what is most necessary; whereas in the West investment is directed toward what is most profitable to capital.

We saw it with big tobacco, we saw it with the fossil fuels industry. When their own internal research showed the harm from their product, the defunded the research and attacked independent researchers coming to the very same conclusions.

Each generation seems to rediscover the riddle of organismal agency: are organisms agents that pursue intrinsic goals—and how could we know? Our 📕 gathers historians, philosophers & scientists to explore this debate—now available in paperback!👇 www.routledge.com/The-Riddle-o... #philsky #HPS #evobio
Book cover of "The Riddle of Organismal Agency: New Historical and Philosophical Reflections" (Routledge, 2025). The book belongs to the "History and Philosophy of Biology" series. The editors are Alejandro Fábregas-Tejeda, Jan Baedke, Guido I. Prieto, and Gregory Radick. The design features a geometric pattern of interlocking, multicolored triangles and rectangular prisms in shades of red, yellow, teal, white, and pink. The Routledge logo appears in the lower right corner.
