The total-evidence approach to divergence time dating uses molecular and morphological
data from extant and fossil species to infer phylogenetic relationships, species divergence …

It has long been appreciated that analyses of genomic data (eg, whole genome sequencing
or sequence capture) have the potential to reveal the tree of life, but it remains challenging …

The emergence of islands has been linked to spectacular radiations of diverse organisms.
Although penguins spend much of their lives at sea, they rely on land for nesting, and a high …

Three skeletons collected from the late Oligocene Kokoamu Greensand of New Zealand are
among the most complete Paleogene penguins known. These specimens, described here …

Despite its current low diversity, the penguin clade (Sphenisciformes) is one of the groups of
birds with the most complete fossil record. Likewise, from the evolutionary point of view, it is …

We present the first detailed description of Perudyptes devriesi, a basal penguin from the
middle Eocene (~ 42 Ma) Paracas Formation of Peru, and a new analysis of all published …

Sphenisciformes (penguins) are flightless sea birds widely distributed in the Southern
Hemisphere. These birds have completely lost the capacity for aerial flight. Instead, they …

Two biogeographical units are generally recognized in the present shelf area of Argentina:
the Magellanian and Argentinian Provinces. The two provinces differ in their fossil record …

Since at least the middle-Miocene, the Antarctic Polar Front (APF) and the Subtropical Front
(STF) appear to have been the main drivers of diversification of marine biota in the Southern …
