Wolves and Dogs

Some recent research has suggested that dog friendliness may be the result of something similar to Williams syndrome, a genetic disorder in humans that causes hyper-sociability, among other symptoms. People with the syndrome seem friendly to everyone, without the usual limits.

There are two questions the scientists want to explore. One, said Dr. Karlsson: ”How did a wolf that was living in the forest become a dog that was living in our homes?”

The other is whether fear and sociability in dogs are related to the same emotions and behaviors in humans. If so, learning about dogs could provide insights to some human conditions in which social interaction is affected, like autism, or Williams syndrome, or schizophrenia.
