The nature and prevalence of diversification rate shifts across the Tree of Life.
Article in Evolution letters, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Strong disparity in species richness among organisms is well documented, but heterogeneity in the underlying diversification process is less understood. Using novel probabilistic methods, we investigate clade-specific diversification rate shifts in several species-rich phylogenies, together representing over 300,000 species across the Tree of Life. We find that diversification rate shifts are extremely prevalent across all clades, with more frequent changes in younger clades and an overall excess of upshifts, resulting in an apparent acceleration of net diversification rates. We also reveal that heterogeneity in diversification rates is related to the tempo of diversification itself. While we find support for more prevalent shifts in speciation rates than extinction rates and more upshifts than downshifts, this is partially due to data insufficiency and inference challenges. Our insights are fundamentally enabled by studying numerous large phylogenies with rigorous statistical methods, showing widespread prevalence of diversification rate shifts across the Tree of Life.
