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 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...

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.

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
