Adélie penguin
The Adélie penguin (''Pygoscelis adeliae'') is a species of penguin common along the entire Antarctic coast, which is their only residence. They are among the most southerly distributed of all seabirds, along with the emperor penguin, the south polar skua, the Wilson's storm petrel, the snow petrel, and the Antarctic petrel. They are named after Adélie Land, in turn named for the wife of French explorer Jules Dumont d'Urville who discovered these penguins in 1840.〔''(Adélie, adj. and n. )'' OED Online.

==Taxonomy==
The Adélie penguin is one of three species in the genus ''Pygoscelis''. 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 Adélie penguins split off from the other members of the genus around 19 million years ago.
