Brief Historical Overview

The first mammals appeared there 200 million years. They ate grass and populated much of the globe.

Species diversification gave birth, there are 100 million years to Creodonts that them eat meat. It was the first carnivorous.

The Creodonts evolved in turn, and 50 million years before our era, they left room for Miacidés, small carnivores in the size and appearance of the weasel. They settled in North America and Eurasia that they gained through the Bering Strait, not yet immersed in the day. That was 35 million years.

For 25 million years following this family of carnivores took root in different regions, evolving according to climate, terrain and different game that he had to adapt. The Miacidés became Cynodictis then Hesperocyon and Tomarctus.

There are 10 million years ago, people returned to North America, the chance of their migration, settled there. Appeared then Lépophagus Canis, which can be regarded as the ancestor of the modern canine. In turn, it went over the Bering Strait.

In North America its descendants will be the Jackal and the Wolf American.

In Eurasia the Canis Lupus Chanco and Canis lupus pallipes. This is the origin of Dogs called primitive because domestication has never been successful and their characteristics have remained very close to the initial stage, such as the Australian Dingo, appeared there are 12 to 13,000 years.

In Europe the Canis Cipio generate Coyote Canis Etruscus and children of European wolf.

The period that follows unfortunately does not define the precise lineage and evolution of different species. Who's Jackal, Coyote or Wolf, is the grandfather of Canis Familiaris, the true ancestor of our modern dog?

The current scientific theories, supported by recent discoveries in the course of excavations tend to lean towards the Wolf.
