The species concept is the cornerstone of biodiversity science, and any paradigm shift in the
delimitation of species affects many research fields. Many biologists now are embracing a …

Synthesizing trait observations and knowledge across the Tree of Life remains a grand
challenge for biodiversity science. Species traits are widely used in ecological and …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

We developed a linear-time algorithm applicable to a large class of trait evolution models,
for efficient likelihood calculations and parameter inference on very large trees. Our …

Historical biogeography has a diversity of methods for inferring ancestral geographic ranges
on phylogenies, but many of the methods have conflicting assumptions, and there is no …

We combined new sequence data for more than 300 muroid rodent species with our
previously published sequences for up to five nuclear and one mitochondrial genes to …

Adaptive radiation plays a fundamental role in our understanding of the evolutionary
process. However, the concept has provoked strong and differing opinions concerning its …

We present mvmorph, a package of multivariate phylogenetic comparative methods for the r
statistical environment. mvmorph is freely available on the cran package repository …

Many evolutionary biologists are concerned with the tremendous amount of diversity of
species, and their phenotypes, that we can currently observe in nature, and one of the most …

Large-scale adaptive radiations might explain the runaway success of a minority of extant
vertebrate clades. This hypothesis predicts, among other things, rapid rates of morphological …
