In essence, it was around 10 mya that the fox lineage split from the wolf-dog lineage.

Readers interested in a more detailed appraisal of dog evolution are directed to Xiaoming Wang and Richard Tedford’s authoritative account in their 2008 book and I recommend the reader visits Wiki Pedia and The Searching Wolf.

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.

Fox domestication Living with the wild: interacting with wild foxes Interaction with other Species Small and Medium-sized Mammals Livestock Gamebirds Arctic Foxes and other Carnivores Deer Native Animals in Australia Plants and Invertebrates Questions and Answers Evolution and Early Distribution: Dogs and cats are Carnivorans, that is, they’re members of the taxonomic order Carnivora (note this is different to simply being a carnivore, or meat-eater, which is not a taxonomic grouping), which is one of 29 orders within the class Mammalia.

The caniforms subsequently diverged into three lineages (which we call subfamilies): the Hesperocyoninae (‘western dogs’); the Borophaginae (‘bone-crushing dogs’); and the only one still around, the Caninae, which includes the dogs, wolves, foxes, etc.

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.

This radiation was probably in response to a vacant niche opening up as the borophagines started to die-out, and not only marked the birth of all the dog species we know today but also heralded the appearance of three modern-day genera in the south-western USA: (true foxes).
