and is thought to stem from the now extinct small fox-like , which lived in North America.
During the late Miocene, around 10 mya, something important happened: the third, and for our purposes most important, canid radiation began.
Aubry’s data reveal more than just the distribution of foxes in pre-history, it also elucidates the relatedness of the animals currently inhabiting North America (see: Taxonomy).
In their 1982 comparison of Red and Arctic ( comes from the Old World and dates to the early Pleistocene (between 1.8 and 1 mya) of Hungary and, in her 2008 study of Red fox dentition, Polish Academy of Sciences mammalogist Elwira Szuma suggested that the current line evolved either in Asia Minor or North Africa around this time.
As fox populations rose in Eurasia, those in North America appear to have dwindled.
Recent genetic work by Keith Aubry and his colleagues at the Pacific Northwest Research Station in Washington, however, has revealed new information on the spread of the Red fox in North America.
Aubry’s data suggest that this species first reached North America during the Illinoian glaciation that lasted from roughly 300,000 to 130,000 years ago; during the next 30,000 years (the Sangamon interglacial period) the foxes spread south from Alaska, across what is now the contiguous USA.

Briefly, the creature that taxonomists currently think gave rise to modern-day dogs was a medium-sized (about the size of a coyote) grassland predator of North America called that appeared during the late Eocene, some 36 mya.
