　　When a dog and its owner look at them, these fond eyes will cause the brains of dogs and people to secrete a hormone called oxytocin. Emotional connection, this study shows for the first time that oxytocin can work between different races, and the study shows that this effect evolves with the domestication of dogs.

　　As a research writer, Mihoagasawa of Azabu University said: “Dogs adapt to the coupling mechanism between humans, so it can coexist well with humans, which means that humans may have evolved some way to make us possible. The dog’s close relatives are wolves, and there are no certain behaviors or brain responses to humans, even people raised by humans. When human mothers and children look at each other, their brains secrete oxytocin, which is the same as the mother’s Bonds are related to other trusting relationships. Similarly, in rodent studies, studies have shown that attachment behaviors cause mothers’ brains to secrete oxytocin, which is a hormone that allows mothers to participate in parenting behaviors and can cause children to secrete more With more oxytocin, children will become more attached to their mothers. Agasawa and her colleagues conducted a series of experiments to understand whether this hormone can attach parents’ dependence on pets to humans. “Oxytocin enhances bitches. The study found that the owner secreted more oxytocin, which confirmed the existence of a positive feedback loop between humans and female dogs. "

　　However, the use of the second experimental oxytocin did not increase the male dog’s sight of strangers. This hormone can keep dogs alert and aggressive towards strangers. In addition, the appearance of a stranger will hinder people’s desire to stare at it. Nagasawa said: “The secretion of hormones seems to depend on the dog’s owner. Therefore, when a stranger appears, it is a male dog. At first glance, it seems very vigilant. , And satisfies most of the gaze behavior of male dogs caused by oxytocin, and the right is their owner

　　The researcher said that the results of the study are the origin and evolution of dogs. He said that he can provide clues for scientific research.
