) to appear on the continent migrated (again, presumably across the Bering land bridge) from Europe at the end of the Pleistocene (around 1 mya) and, from here, Red and Arctic foxes colonised much of North America.

The large ice sheet that covered most of Canada and the northern fringes of the USA from around 100,000 to 10,000 years ago (during the Wisconsin glaciation) kept the Red foxes in Alaska (the population of which was added to by a second wave of colonisation from Eurasia) separate from those in the southern USA.

Recent work by Louis de Bonis and colleagues at the Université de Poitiers in France has suggested that the foxes and other canids first spread throughout Africa, before invading Europe via a trans-Mediterranean route towards the end of the Miocene.

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.

As fox populations rose in Eurasia, those in North America appear to have dwindled.

Previously it was believed that the first modern Red foxes (i.e.
