'Golden Hour' of all species

Who can be sure what makes these people laugh so happily, but few people may disagree that laughing often helps people feel good.

Monkeys, dogs and fish all enjoy life, said Jonathan Balcombe, a researcher at the Physicians Committee for Responsible Medicine, based in Washington, DC.

Man's best friend is always full of emotions

Many scientific studies indicate that dogs are very emotional. 'Dog owners understand that when they see how they move, how to wave their tails and their facial expressions and barks. We can distinguish what dogs are feeling - they are sad or happy, excited or depressed or guilty, 'said Balcombe. Even people who have never adopted a dog can read their attitudes, he added. ' We can only imagine how dogs understand each other, but they understand each other, I mean when we are together (thanks to the sensitive sense of smell, for example), they get more information than we do .'

The horse's heartbeat falls when groomed

To find biological evidence that animals can feel joy, look at horses. Balcombe stressed that studies have found that, for example, horse hearts beat more slowly when they are brushed and dried off their hair and mane. The reduction in heart rate " is said to respond when feeling comfortable and relaxed," he said.

The mouse likes to be tickled

When the pups - the rodents that humans hate so much - ran around, struggling with each other, they were actually tickling each other, according to a study led by Jaak Panskeep, at Washington State University. It turned out that the mice loved being tickled. This study, according to Balcombe, shows that mice that are often tickled on their hips will run to the researchers' hands much faster than those that are tickled at the neck.

Monkey likes to be cuddled

Observers claim that monkeys love to be cuddled, as in the picture above, and like to give the message. Balcombe said that these gestures make the chemistry and hormone levels in monkey blood change in the " like we can see when we are stroked ". Biochemical findings, he added, are another door to understanding how animals enjoy fun.

Sexual behavior is not just for the purpose of maintaining the race

As humans know, sexual behavior is not always for children. The animal kingdom is full of examples of such animals, Balcombe said. For giraffes, homosexual behavior is more common than heterosexual. And even when this [mating] to maintain the race, Balcomebe said, most animals probably still don't agree to find pleasure with the birth of a child.

Likes are ' cleaned '

Balcombe's research on animal pleasure is somewhat against the tendency to analyze animal behavior based on complex evolutionary terms. For example, the relationship between a ' clean-up ' fish and its ' customers ' is often described as ' mutual benefit '. The fish that 'clears' the food is the parasites that live on the body of the fish, and the fish is washed. ' But I think that the reason the owner gives is [' rubbing '] because they like it. I don't think the bosses realize any health benefits , 'he said. ' So I think it is pleasure that motivates this relationship .'

Ferrets chase each other for fun

The ferrets in this picture are chasing each other around the tree to make fun, Balcombe said. Although play is based on evolution, not from learning to hide from an enemy or a prey, Balcombe argues in a recent article in Applied Animal Behavior Science (Dynamic Behavior Science). Practices) that animals' do not play consciously for essential reasons: they play because they are happy .

Don't believe the dolphin's face

Is this big nose dolphin happy to be with its newborn baby? Although there have been many fantasy works about dolphins' intelligence and hardly anyone suspects that dolphins can feel joy, Balcombe said that the expression of this species does not show much emotion inside. He said that dolphins have little change in expression. " It is important to understand how animals feel about understanding them, understanding their biology and understanding how they live ," he said.
