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 …

Linking interspecific interactions (eg, mutualism, competition, predation, parasitism) to
macroevolution (evolutionary change on deep timescales) is a key goal in biology. The role …

The origin and expansion of biological diversity is regulated by both developmental
trajectories, and limits on available ecological niches,,,,. As lineages diversify, an early and …

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 …

The golden jackal of Africa (Canis aureus) has long been considered a conspecific of
jackals distributed throughout Eurasia, with the nearest source populations in the Middle …

The history of biodiversity is characterized by a continual replacement of branches in the
tree of life. The rise and demise of these branches (clades) are ultimately determined by …

Morphological diversity may arise rapidly as a result of adaptation to novel ecological
opportunities, but early bursts of trait evolution are rarely observed. Rather, models of …

The molecular clock is the only viable means of establishing an accurate timescale for Life
on Earth, but it remains reliant on a capricious fossil record for calibration.'Tip …

Here, I combine previously underutilized models and priors to perform more biologically
realistic phylogenetic inference from morphological data, with an example from squamate …

The Cenozoic marked a period of dramatic ecological opportunity in Earth history due to the
extinction of non-avian dinosaurs as well as to long-term physiographic changes that …
