Happy to share my new article on how morphological diversification proceeds during evolutionary radiations: "The diffused evolutionary dynamics of morphological novelty" www.pnas.org/doi/10.1073/... 🧵 1/12
The diffused evolutionary dynamics of morphological novelty | PNAS
Rates of evolution are fundamental to understand the processes that shaped the history of life. The predominant view holds that high rates of pheno...

The US has criminally murdered several latin americans, including Colombians. Most remain in silent complicity, those few who denounce it are called narco-terrorists.

As tensions escalate between Colombia and the United States, Colombia has recalled its ambassador from the U.S. back to Bogotá. Democracy Now! speaks to Ambassador Daniel García-Peña about the decision.

Government style ad in watercolour. Image of a burglar stealing a painting from the wall of a home. Tagline: "It's not theft... if you say you're using it to train your AI algorithm". Body text: "Theft is now legal, so we can boost the economy by eliminating jobs. If that doesn't make any sense, ask a chatbot to explain it to you." HM government logo in the corner.

L'ex-futur prix Nobel de la paix, Donald Trump, menace à présent la Colombie après le Venezuela sous le même prétexte du narcotrafic. Les menaces directes contre le Président Gustavo Petro n'ont qu'un sens : punir son engagement ferme et avancé contre le génocide à Gaza.

We call this hypotheses the 'Zarathustran hypothesis', following Nietzsche’s idea that the maintenance of life does not merely follow from conservation, but rather from constant renovation, movement, and expansion. 3/3

This species-level tendency to increase extinction and decrease speciation rates with age can be explained if evolutionary change concentrates at speciation, with a paucity of speciation causing lineages to lag behind a continuously reshaping (biotic and abiotic) environment. 2/3

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

The right (yes, “center” too) has become so utterly cynic (and, as usual, unimaginative) that they assume fulfilling the basic rights of people is not possible (nor desirable) and thus that anyone interested in providing just that must be lying or share their hidden intentions.

Journalists are being massacred in Gaza and the U.S. is doing nothing to stop the bloodbath it’s bankrolling.
