The Vulpinae, or fox "subfamily" of the Canidae, split from the rest of their doggy brethren about 12 million years ago.
Those original vulpines are long gone, but their descendants are among the most widespread of mammal groups in the world.
Grey foxes are among the oldest species, having remained unchanged for about six million years.
The youngest species is
thought to be the arctic fox, a scant 250,000 years old. Arctic foxes eke out a living in some of the coldest places in the
world, while their cousins the fennecs and bat-eared foxes can be found in some of the hottest and driest. And in between,
some 20 other species of foxes (approximately) can be found. They live on every continent except for Antarctica (having been
introduced to Australia in the mid-nineteenth century). They even live, quite happily, in the heart of our cities.
As I have more time, this page will accumulate some of the information about foxes that I have gathered together over the
years. Keep checking back, and keep an eye out for foxes!
