The rich diversity of morphology and behavior displayed across primate species provides an
informative context in which to study the impact of genomic diversity on fundamental …

In cases of severe wildlife population decline, a key question is whether recovery efforts will
be impeded by genetic factors, such as inbreeding depression. Decades of excess mortality …

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 …

The ancestors of marine mammals once roamed the land and independently committed to
an aquatic lifestyle. These macroevolutionary transitions have intrigued scientists for …

Though narwhal have survived multiple ice ages, including 2.5 Ma and the last interglacial
period with warming temperatures, Arctic climate change during the Anthropocene …

Studies of cetacean evolution using genetics and other biomolecules have come a long way—
from the use of allozymes and short sequences of mitochondrial or nuclear DNA to the …

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 …

Phylogenomic analyses routinely estimate species trees using methods that account for
gene tree discordance. However, the most scalable species tree inference methods, which …

The deep sea has been described as the last major ecological frontier, as much of its
biodiversity is yet to be discovered and described. Beaked whales (ziphiids) are among the …

Understanding how and why menopause has evolved is a long-standing challenge across
disciplines. Females can typically maximize their reproductive success by reproducing for …
