The largest known dinosaurs weighed at least 20 million times as much as the smallest,
indicating exceptional phenotypic divergence. Previous studies have focused on extreme …

The time is past when a research program in systematics should be based on only a few
genes, extant taxa, and ultrametric trees. Cheap genome sequencing, powerful statistical …

Relative brain size has long been considered a reflection of cognitive capacities and has
played a fundamental role in develo** core theories in the life sciences. Yet, the notion …

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

Phylogenetic comparative methods are increasingly used to give new insights into the
dynamics of trait evolution in deep time. For continuous traits the core of these methods is a …

Behavior is one of the major architects of evolution: by behaviorally modifying how they
interact with their environments, organisms can influence natural selection, amplifying it in …

A substantial amount of phenotypic diversity results from changes in gene expression levels
and patterns. Understanding how the transcriptome evolves is therefore a key priority in …

The detection of evolutionary shifts in trait evolution from extant taxa is motivated by the
study of convergent evolution, or to correlate shifts in traits with habitat changes or with …

One of the enduring questions that has driven neuroscientific enquiry in the last century has
been the nature of differences in the prefrontal cortex of humans versus other animals [1] …

Relative brain sizes in birds can rival those of primates, but large-scale patterns and drivers
of avian brain evolution remain elusive. Here, we explore the evolution of the fundamental …
