The genus Pygoscelis ("rump-legged") contains three living species of penguins collectively known as "the brush-tailed penguins".
Mitochondrial and nuclear DNA evidence suggests the genus split from other penguins around 38 million years ago, about 2 million years after the ancestors of the genus Aptenodytes. In turn, the Adelie penguins split off from the other members of the genus around 19 million years ago.
The three extant species are:
Extinct species:
The latter two are tentatively assigned to this genus.
