without any obvious assistance from humans) around 10,000 years ago.Indeed, other fossil data imply that the ice forced foxes into the warmer southern regions of Europe (e.g.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.
So, the result was two isolated populations (or clades): one in Alaska (Holarctic clade) and one in the south (Nearctic clade).

There is then something of a hiatus in the vulpine fossil record until the early Pliocene (about 4 mya), with foxes from China and Turkey among the earliest Eurasian specimens.
The origins of our modern-day Red fox (, which lived in southern Europe at the end of the Pliocene, around 2.6 mya – this species was first discovered in deposits from Italy in the late 1800s, but remains were subsequently found in France, Spain and Greece.
