Variation in the rate of species diversification underlies many large-scale patterns in the
organization of biological diversity. Here, I explore the phenomenon of diversity-dependent …

Previous analyses of relations, divergence times, and diversification patterns among extant
mammalian families have relied on supertree methods and local molecular clocks. We …

Species selection as a potential driver of macroevolutionary trends has been relegated to a
largely philosophical position in modern evolutionary biology. Fundamentally, species …

A number of methods have been developed to infer differential rates of species diversification
through time and among clades using time-calibrated phylogenetic trees. However, we …

The fossil record is the primary source of information on how biodiversity has varied in deep
time, providing unique insight on the long-term dynamics of diversification and their drivers. …

… software installed, you can download article citation data to the citation manager of your

Understanding the dynamics of speciation, extinction and phenotypic evolution is a central
challenge in evolutionary biology. Here, we present BAMM tools, an r package for the …

Far more species of organisms are found in the tropics than in temperate and polar regions,
but the evolutionary and ecological causes of this pattern remain controversial 1 , 2 . …

Several evolutionary theories predict that rates of morphological change should be positively
associated with the rate at which new species arise. For example, the theory of punctuated …

… of the gamma distribution (scale and shape), and this fitted model can be directly
compared to models that assume homogeneity of rates or that allow rates to vary over time (Rabosky …
