Gestures are commonly used in a wide range of scenes to convey something to someone. However, because grammatical rules do not exist, although it does not correspond to the language, the meaning is firmly present. Chimpanzees stroking the mouth to request food,GroomingWe will move the arm to request. And it turned out that Bonobos also do similar gestures.

"The possibility that the same gesture of the same meaning was used even by the race which is the common ancestor of these apes and humans I point out.

But,Humboldt University BerlinMr. Richard Moore questioned this research, "It is not demonstrating that Bonobo and chimpanzee understand each other 's gestures." In this study, Bonobos and chimpanzees did not mention gestures and the corresponding vocalizations to be done accordingly, and they have not arrived yet.

Mr. Graham said, "The data presented in this paper is interesting and will be the" starting line for future research ", says that, now, it is said that for human beings apes gestures, We are starting to investigate whether it shows a reaction.
