The Red Fox (Vulpes vulpes) is the largest of the true foxes, as well as being the most geographically spread member of the Carnivora, being distributed across the entire northern hemisphere from the Arctic Circle to North Africa, Central America, and the steppes of Asia. Its range has increased alongside human expansion, having been introduced to Australasia, where it is considered harmful to native mammal and bird populations. Because of these factors, it is listed as Least Concern for extinction by the IUCN. It is listed among the 100 "world's worst alien invasive species". The red fox originated from smaller-sized ancestors from Eurasia during the Middle Villafranchian period, and colonised North America shortly after the Wisconsian glaciation. Among the true foxes, the red fox represents a more progressive form in the direction of carnivory. Apart from its large size, the red fox is distinguished from other fox species by its ability to adapt quickly to new environments and, unlike most of its cousins, is not listed as endangered anywhere. Despite its name, the species often produces individuals with abnormal colourings, including albinos and melanists. 45 subspecies are currently recognised, which are divided into two categories: the large northern foxes, and the small, primitive southern foxes of Asia and the Middle East.
