Why pet pigs are more like wolves than dogs

60-Second Science


Starring John that Timmy and of course, laughing. It's a classic television trope. Timmy is fallen down a well lassie save him herself. So she runs defined help. Actually. Timmy never did fall down a well in the entire run of the TV show. But the idea that a dog could seek help from a human does have a solid basis in science in what's known as the unsolvable task experiment. A dog I learns how to open a puzzle box with a tasty treat inside. The puzzle is secretly switched for another that's impossible to solve. After becoming frustrated dogs, shift their attention away from the puzzle and onto a nearby human than back to the puzzle. The dog attempts to shift the humans attention to the puzzle as request for help human infants do the same thing. Such efforts are called Referential Communication. So of dogs behave this way, you might expect the same from their close relatives wolves. But when researchers tested wolves raised by humans, the animals just kept trying to solve the puzzle never seeking help since the dogs and wolves were all raised. The same way by the same people domestication must be responsible for the behavior. So researchers began studying domesticated creatures, other animals, species like some horses boats have been Stephen this this. There were no dieted combinations with those Paula Peres Fraga and he thala gist at. Lawrence University in Hungary. Pet Cats respond more like wolves, dogs, cats are domesticated, but they are not social like dogs and wolves pigs however are social. When big save in the wine or even like why endorse this animals lives in group on they need to communicate. We've they're gonNA specifics to be able to leave, which is why the researchers decided compare pet dogs with pet pigs. While the pigs revealed, they work capable of referential communication. They didn't actually turn to people for help. Once. The test became unsolvable. They acted more like wolves determined to find a solution on their own. The results were published in the journal Animal Cognition. Well, the medication man's is slightly to leave the days Connecticut change in the in the species from their wild relatives, and normally these genetic change has appear because of human pressure most domesticated animals, including dogs, cats, horses, goats, foxes, and so on. Show similar anatomical and physiological changes associated with domestication. But Franca says, her study shows that the domestication process can precede along different pathways in different animals and that could explain by domestication and sociality alone can't explain why dogs react the way they do when faced with an unsolvable puzzle. Fraga thinks that it could be related to their domestication history. Their domestication was different speaks has been domestic. Normally. Like mostly for being us meets resource. It was only later that we started treating some pigs as pets dogs on the other hand were treated as companion animals from almost the beginning which appears to explain their willingness to ask for help.
