The old saying “man is a wolf to man”, or better known in its latin form “homo homini lupus” has been proven right many times. Also, “a dog is a man’s best friend” is something that many dog owners and dog lovers will confirm. A few thousand years ago, dog was a wolf that was tamed by man. But according to evolutionary biologist’s new research, looks like man is not as responsible for the existence of his friend dog as it was belived, but it was simply- nature.
Autism is a disorder characterized by troubles with social interaction and communication. Often there is also restricted and repetitive behavior. On the other hand, there is a disorder, which you could say, is the complete opposite of autism- Williams syndrome. Williams syndrome affects an estimated 1 in 10,000 people. Affected individuals have outgoing, engaging personalities and tend to take an extreme interest in other people. They will act with a complete stranger as with a very close friend. Besides that, they have a unique shape of their face (they look a little like elves). They also have mild to moderate intellectual disability or learning problems.
But what all this has to do with dogs? It has been shown that dogs have the genetic disorder that is responsible for Williams syndrome in people. When scientists analyzed the DNA from wolves and dogs, the analyses showed that all dogs, unlike wolves, have this genetic mutation, which makes them very friendly with people. This means we didn’t tame wolves; there were wolves with this genetic mutation thousands of years ago, that wanted to play and be friends with people, unlike those without it. We started cross breeding wolves with Williams syndrome and stimulated the creation of new generations carrying this disorder.
