The precise pattern and timing of speciation events that gave rise to all living placental
mammals remain controversial. We provide a comprehensive phylogenetic analysis of …

A comprehensive revision of the localities of discovery of fossil mysticetes is presented
together with a highly inclusive phylogenetic analysis in order to provide the basis for a …

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 …

The evolution of cetaceans, from their early transition to an aquatic lifestyle to their
subsequent diversification, has been the subject of numerous studies. However, although …

To discover interordinal relationships of living and fossil placental mammals and the time of
origin of placentals relative to the Cretaceous-Paleogene (K-Pg) boundary, we scored 4541 …

Orcas are large, deep-diving cetaceans who are known for their global distribution, wide-
ranging behavior, intelligence, and social complexity. They possess one of the largest and …

The largest animals are marine filter feeders, but the underlying mechanism of their large
size remains unexplained. We measured feeding performance and prey quality to …

Large datasets are required to solve difficult phylogenetic problems that are deep in the Tree
of Life. Currently, two divergent systematic methods are commonly applied to such datasets …

A new, fully dated total-evidence phylogeny of baleen whales (Mysticeti) shows that
evolutionary phases correlate strongly with Caenozoic modernization of the oceans and …

INTRODUCTION The iterative evolution of secondarily marine tetrapods since the Paleozoic
offers the promise of better understanding how the anatomy and ecology of animals change …
