Quantifying phenotypic evolutionary rates and their variation across phylogenetic trees is a
major issue in evolutionary biology. A number of phylogenetic comparative methods (PCM …

Like catarrhines, some platyrrhines show exposed and reddish skin, raising the possibility
that reddish signals have evolved convergently. This variation in skin exposure and color …

Survivorship biases can generate remarkable apparent rate heterogeneities through time in
otherwise homogeneous birth-death models of phylogenies. They are a potential …

Reconstructing the tempo at which biodiversity arose is a fundamental goal of evolutionary
biologists, yet the relative merits of evolutionary-rate estimates are debated based on …

Bifidobacteria, which commonly inhabit the primate gut, are beneficial contributors to host
wellbeing. Anatomical differences and natural habitat allow an arrangement of primates into …

A distinctive trait in primate evolution is the expansion in brain mass. The potential drivers of
this trend and how and whether encephalization influenced diversification dynamics in this …

Afro-Eurasian monkeys originated in the Miocene and are the most species-rich modern
primate family. Molecular and fossil data have provided considerable insight into their …

We evaluate the total probability of human extinction from naturally occurring processes.
Such processes include risks that are well characterized such as asteroid impacts and …

The uneven distribution of species in the tree of life is rooted in unequal speciation and
extinction among groups. Yet the causes of differential diversification are little known despite …

Recognizing evolutionary trends in phenotypic means and rates requires the application of
phylogenetic comparative methods (PCMs). Most PCMs are unsuited to make full use of …
