Dolphins have discovered the beginnings of language communication.

    Marine biologists from Florida International University and the University of Southern Mississippi found that bottlenose dolphins communicate aloud to each other during a joint task. This means that these marine mammals have a special type of vocalization dedicated to problem solving.

    The experiment involved six captive dolphins who tried to open a can of food. The canister was arranged in such a way that it opened, if you pull the ropes sticking out of its ends, in different directions at the same time.

    During the 24 approaches of the experiment, all six experimental dolphins were present. Of these, only two were able to cope with the canister and get to the food. However, this couple worked very fruitfully - together they opened the canister in 20 cases, for which they needed up to 30 seconds. In another approach, another dolphin managed to open the canister on its own, which was quite difficult to do and took much longer.

    Scientists have registered an increased level of vocalizations issued by dolphins during the joint solution of the problem. During individual approaches, or when the cans were not in the pool, the dolphins did not use so many sounds.

    Biologists have concluded that verbal communication is directly related to the solution of the problem - when one of the dolphins opened the canister on their own, the dolphins who were present did not make any sounds (it's nice when you don’t get bored with tips). Thus, scientists have concluded that vocalization does not have a social function.

    The discovery complements the information about the sounds made by dolphins. It is already known that they perform an echolocation function and serve for social communication between individuals. Now it is clear that one more purpose of them is to communicate with each other to organize cooperation in solving complex problems.
