Habits are making a derivative of ancient dogs, like wolves and modern dogs, a hiperkarnivora or 70 percent of the animals that eat meat.

This conclusion was obtained after the team Munoz-Doran compose 'pedigree' dogs that describes the relationship between the more than 300 species of dogs. "We found a common evolutionary history among a number of types of dogs," said Dr. Munoz-Doran.

"Eight million years ago, a lot of open habitats in Asia, Europe, and North America. Competition is getting very tight prey and these conditions must be ancient dogs and scout groups when looking for prey," he said.

He explained that, from the habit of hunting in packs, new emerging breed of dog with a different head shape, with a more powerful jaws and canine size larger. They are able to survive natural selection and the dog continued this form into the next generation.
