This study shows that larger populations take longer to speciate, challenging the idea that ecological speciation drives much of species diversity.

The paper reevaluates evidence for codiversification in mycorrhizal symbioses by analyzing 29 networks and finds cophylogenetic signal instead of phylogenetic congruence.

The paper uses molecular clocks and diversification models to show steady eukaryote diversification starting in the mid-Proterozoic, challenging the view of limited innovation during this era.

The paper introduces an Empirical Bayes framework for analyzing high-dimensional trait evolution, showing it is faster and more efficient than existing methods.

This paper introduces P3CA, a probabilistic and phylogenetic PCA method for high-dimensional trait evolution, showing improved accuracy in parameter estimation and missing data reconstruction.

This paper introduces a multi-type fossilized birth-death model to jointly infer phylogenies and diversification rates with fossils and extant species, showing improved accuracy when morphological data are available.

The paper analyzes 27 radiations using a new fossilized birth-death model to show that clade diversity follows rise and decline dynamics driven by species-level processes rather than clade-level mechanisms.

The paper reconstructs ancestral mutualistic networks and finds they maintain modular structure over millions of years due to evolutionary conservatism of interactions.

The paper introduces the Occurrence Birth-Death Diffusion process to integrate fossil data into diversification analyses, showing fossils are essential for accurate diversification rate and richness trajectory inference.

This paper shows that graph neural networks with a new pooling method can accurately estimate diversification parameters in complex models where likelihoods are intractable.

This paper introduces F-ClaDS, a new diversification model for phylogenetic inference, and applies it to Nimravidae fossils to show hypercarnivory drives speciation but also increases extinction risk.

The paper examines how speciation completion rates affect macroevolutionary diversification by comparing standard birth-death models with a protracted birth-death model.

This paper introduces a maximum likelihood method to estimate competition's effect on trait evolution by integrating phylogenetic and phenotypic data, showing improved model performance in adaptive radiations.
