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

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.

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

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.
