Variation in macroevolutionary dynamics among extant primates

ABSTRACT: Abstract

Objectives

This study examines how speciation and extinction rates vary across primates, with a focus on the recent macroevolutionary dynamics that have shaped extant primate biodiversity.

Materials and methods

Lineage‐specific macroevolutionary rates were estimated for each tip in a tree containing 307 species using a hidden‐state likelihood model. Differences in tip rates among major clades were evaluated using phylogenetic ANOVA. Differences among diurnal, nocturnal, and cathemeral lineages were also evaluated, based on previous work indicating that activity pattern influences primate diversification.

Results

Rate variation in extant primates is low within clades and high between clades. As in previous studies, cercopithecoids stand out in having high
