The sounds that monkeys make carry messages

Brut America

Monkeys give loud alarm calls in case of danger, combine sounds to convey more information, learn not to interrupt each other. Here is the complex reality of animal language.   With ARTE

00:00In several species of non-human primates, we find so-called language properties that

00:22are ultimately not human-like.

00:52The playback of the day was a series of cracks.

01:13The male, in particular, resumed the cry of alarm that signals a leopard, and these

01:20females reacted immediately.

01:27Monkeys use it to tell themselves that they have to be careful, but no need to hide.

01:41It's this cry that sounds a bit like that.

01:54Visually, it is represented in the form of an arch.

02:03But the fine structure of the arch, as we can see in these different examples, is under

02:13social influence.

02:14Two females who are friends will copy each other.

02:17On the right and on the left, we see different forms of arches of two females copying each

02:22other.

02:23They will avoid cutting each other's throats, they will respect a round of speech, and the

02:37priority is usually given to the elderly, who will vocalize first.

02:42These are rules that young people will have to learn.

02:45Young people, for example, will cut their throats 12 times more than adults, the time

02:51it takes to learn the right way to vocalize in society.
