Why dogs are friendly - it's written in their genes

Being friendly is in dogs' nature and could be key to how they came to share our lives, say US scientists.

Dogs evolved from wolves tens of thousands of years ago.

During this time, certain genes that make dogs particularly gregarious have been selected for, according to research.

This may give dogs their distinctive personalities, including a craving for human company.
"Our finding of genetic variation in both dogs and wolves provides a possible insight into animal personality, and may even suggest similar genes may have roles in other domestic species (maybe cats even)," said Dr Bridgett vonHoldt of Princeton University.

The researchers studied the behaviour of domestic dogs, and grey wolves living in captivity. They carried out a number of tests of the animals' skills at problem-solving and sociability.
