The dog and the wolf are genetically very similar, but the dog was "another person", and the wolf — no. The researchers believe that University of Massachusetts at Amherst (USA), the whole thing in a different sensory experience, which is experiencing a small wolves and domestic dogs, puppies to the point where it was time to socialize.

As the researchers wrote in the journal Ethology, and wolves, and domestic puppies learn about different experiences at the same time. That is, they begin to understand the smells from two weeks of age, the sound — with a four, full vision is formed only by the sixth week. However, between the cubs and puppies there is a difference in the so-called period of socialization. When a puppy comes home this time, he wanders around without fear acquainted with the environment, every new object makes him curious, be it a person, a horse or a cat. Friendly relations established during this period, will remain in the dog for life. But when the study period ends, any new signal will first cause suspicion and fear.
We also have a cub period of socialization, but (and this is important) if it begins in dogs four weeks of age, the wolves — in two weeks. Cubs at this age are deaf and blind, and the only thing they explore the world around us, is the nose. When the cubs begin to hear and see the very first auditory and visual signals to cause fear and alarm. The usual puppies of his master, for example, during the period of socialization and see, and hear, and smell, but because social ties with the owners (and with them, say, cats) will be stronger. We can say that dogs and wolves adult character is defined childhood impressions — just like humans.
It follows one side, but the important practical conclusion: if you want your dog to the soul in you adored, join her education just at this research and socializing time that puppies coming by the end of the month. With the wolf such a thing can also be done, but it was too troublesome, perhaps two weeks to grow blind and deaf wolf without the help of his mother.
In addition, the data again suggest that it is not so much the number of shared genes, but in their management. It does not matter which genes work, and when and in what order they are included.
