Have you ever wondered how it is that your Golden Retriever, Great Dane or Irish Setter is such a loving creature? Science has found the answer to the question of why dogs are so friendly. In dogs, scientists have found gene mutations that are responsible for dogs being much friendlier and sociable compared to wolves.
At a famous university Princeton have evolutionary biologists gotten to the bottom of the question, why are dogs so friendly. Three years old study led them to the answer. They were watching dogs and wolves, who were raised in the same conditions, and found that they are dogs are much more sociable, focus more of their attention on people and obey commands more consistently.
Researchers have found that the basis for the immense kindness of our four-legged friends is to a large extent of genetic origin. Hypersocial dogs show similar genetic changes to people with Willi syndrome. The latter in an individual causes, among other things, that shows excessive love in all social interactions.
