New Zealand Sea Lion a Newcomer

Date: 1/7/2014

The modern New Zealand sea lion is a relative newcomer to the mainland, replacing a now-extinct, unique prehistoric New Zealand sea-lion that once lived here, according to a new study.
A team of biologists estimates that this prehistoric mainland sea-lion
population became extinct as recently as 600 years ago, and was then
replaced by a lineage previously limited to the waters of the cold
subantarctic.
