Yawn Contagious. Finally, if we accept we tread lightly on the definition of the word “infectious”. Because we know, there is no question here about It transmits the virus Or another microbe. It is simple ” Repetition“ The behavior that actually occurs when a person yawns in response to a yawning. A completely involuntary recurrence, generally stimulated by sight, that behavioral scientists have been able to observe in humans. Is involved, most likely, Mirror neurons.
But men aren’t the only ones who have it Yawn with pleasure . Yawning is a common behavior. Animals yawn, too. Chicken Chimpanzee Or even a cobra. Black too. These are big cats lazyWho spend their time hanging out Soleil . While these ladies, the lionesses, raise the little ones and go hunt. What surprised the team of researchers who were monitoring them was that over short periods of time, lions could yawn again. Especially when wild animals are relaxing. Can we also talk about ‘redundancy’ for them?
Researchers have long believed that reproducing yawning has been a prerogative of humans. Manifestation SympathyFor our loved ones. Feelings we share with those we meet. But studies have already shown that yawning can also be transmitted from humans … to dog. As if to facilitate the interactions we could have with our best friend.
Let’s return to the issue of the possible “recurrence” of yawning between them Felines Researchers have spied for several months, about twenty years black In a private reserve in South Africa, the Makalali Reserve.

Well, it turns out that another lion that is “contaminated” with its yawning will also tend to get up, take a few steps and lie down again. Anyway, this is what the researchers note. A type of “motor synchronization” stimulated by the initial yawning.
This is why behavioral scientists now consider that yawning can actually play a role Social role In the pride of lions. Even with others CashVery social. Yawning can help put people in the same positionWave length. This is important for animals that hunt and raise their young in flocks. Moreover, some believe that the social organization of lions is the root of their domination of their environment.
