Laughter is a reflex, but the reflex is unique in that it serves no obvious biological purpose; it can be called a luxury reflex.
Its only practical function, as far as can be judged, is to provide temporary relief from the burden of utilitarianism.
What creatures can laugh
As it turned out, more than 65 species of animals and birds are capable of laughing.
These include dogs, cows, seals, mongooses and foxes.
The information resource uses recommendation technologies.
Human laughter has always remained a mysterious phenomenon among scientists.
Scientists have compiled a list of 65 animal species that laugh in one form or another.
After analyzing data on play behavior across species, the researchers compiled a review of animals that use vocal signals to invite partners to play and communicate the absence of aggressive intentions.
Which animal can smile
The mimic abilities of animals are very limited.
Many dog and cat owners, of course, will say that yes, they can.
Nevertheless, is it really a smile? Of all the animals, only chimpanzees can “replicate” a human smile - they, like humans, can stretch their lips, revealing their teeth in a wide smile.
Why do rats laugh
The animal may be stressed, and in this state there is no time for fun: if there is a cat wandering nearby or the stomach is rumbling from hunger.
Rats laugh in different ways: sometimes this laughter takes on a malicious connotation, sometimes it is mocking, but more often it is joyful.
