Most people who own pets claim that they are jealous, especially cats, and after all, the need for attention begins with the arrival of the newborn kittens, roaming animals do not work as pets do, and despite the evidence Anecdotal, scientists have long struggled to study and identify emotions in animals, but research has begun to suggest that at least jealousy is a primitive emotion shared by both people and some animals (especially dogs and primates).
It is important to realize that while the terms ‘jealousy’ and ‘envy’ may sometimes be used interchangeably, psychologists see them as very different emotions. Envy is an emotion from two entities that occur when we lack something, whether it is a character trait or something of another person, and jealousy. On the other hand, it requires a social triangle and appears strongly when a person or something threatens a special relationship.
Most jealous research revolves around romantic relationships, but jealousy, of course, can occur in other situations such as between friends, family members, and coworkers. Research shows that children younger than 6 months showed jealousy when their mothers interacted with another baby (that was actually a realistic-looking doll), and this suggests that jealousy is an innate feeling that has evolved to protect any kind of social relationship between connected people, and maybe present in social animals.
In 2014, researchers from the University of California at San Diego modified infant experiences, adapting them to a man’s best friend, and found that dogs acted more jealously when their owners interacted with a fake dog (treating it as real) compared to lanterns or books, and third of the Dogs tried to enter between their owners and the fake dog, and about a quarter of the dogs were trying to bite the fake dog.
For jealous dogs, researchers suspect that dogs may have understood that fake animals were not real dogs or did not have strong bonds with their owners, and scientists documented jealousy in copper Tete monkeys, a monogamous primate species, They use animals to better understand the neurobiology of strong emotion.
In response to his romantic rivals, it is known that male Tete monkeys become aggressive, placing themselves among her comrades and potential competitors, and sometimes restricting their female companions physically to prevent them from moving into exotic males, relative to the research, published on October 2017 in the journal Horizons in Ecology and Evolution, Scientists had male Tete monkeys watching that their female companions interact with strange males for 30 minutes and watch strange females interact with strange males as much as time.
When observing their female peers, monkeys experienced increased levels of testosterone (associated with aggression and companion-related competition) and cortisol (a reference to social pressure), and in addition, brain tests revealed that monkeys increased their activity in an area of the brain associated with social exclusion in humans ( Cortex) and another area associated with aggressive behavior (lateral barrier).
More importantly, studies indicate that a large proportion of pet owners report signs of consistent jealousy in domestic pets, including horses, birds, and cats, and further research into the social feelings of animals other than dogs and monkeys may reveal that jealousy is more prevalent than it looks.
