The Falkland Islands wolf, long extinct, is the only land-based mammal native to the islands. Thanks to new oceanographic information, we know the Falkland Islands weren’t always as isolated from South America as they are today. Determining how close was the key to identifying when the ancestor of the warrah reached the Falkland Islands. Using new mathematical techniques to estimate a “molecular clock” we calculated the age of the split between the mainland fox and the warrah to be around 16,000 years ago, much more recently than previously thought. Previous theories have suggested the wolf somehow rafted on ice or vegetation, crossed via a now-submerged land bridge or was even semi-domesticated and transported by early South American humans. The Falklands wolf quickly went extinct after Europeans arrived on the Islands from the 17th century. description.

He named the place Falkland Islands. We pieced together the puzzle using new data from genetics, fossils and oceanography and discovered the ancestor of the warrah probably walked to the islands across a frozen, narrow marine strait during the last ice age, about 16,000 years ago.
