There are no hedgehogs native to Australia and no living species native to the Americas. However, the extinct genus Amphechinus was once present in North America. Hedgehogs share distant ancestry with shrews (family Soricidae), with gymnures possibly being the intermediate link, and they have changed little over the last 15 million years. [2]
Amphechinus is an extinct genus of hedgehog of the family Erinaceidae, which lived in Asia and Europe during the Oligocene and in North America, Africa, Asia and Europe during the Miocene. The genus contains at least 14 species. It is classified in the subfamily Erinaceinae and in the family Erinaceidae.
While Australia is a continent and not an island, due to its geographical isolation, its unique fauna has suffered an extreme decline in mammal species, 10% of its 273 terrestrial mammals, since European settlement (a loss of one to two species per decade); in contrast, only one species in North America has become extinct since European settlement.
