Unlike dogs and wolves who communicate with their relatives eyes, chimpanzees use sign language. Scientists have made the first dictionary, which provides decoding of primate gestures, carrying a meaning to the interlocutor.
As you know, our closest genetic relatives communicate with gestures. New research has shown that chimpanzees use legs to utter phrases such as "follow me", "stop doing it" or "take it," writes Discovery. The study, conducted by researchers at St Andrews University in Scotland, was published in the journal Current Biology.
Total researchers deciphered the 66 gestures that can work separately or in tandem to transmit more informative messages sent. Sign language to communicate which chimpanzees understand any representative of the species.
The researchers studied a video of more than 4 500 cases of communication in sign language in more than 3400 contacts chimpanzees in Uganda between 2007 and 2009.
If the mother shows her baby legs, it can mean "Scramble to me." Touching the paw of another individual means "scratched me" and nibbling leaves chimps used to attract the attention of the opposite sex.
According to the researchers, have done observations showed a clear relationship between some gestures and subsequent actions of the interlocutor. However, part of gestures can be perceived ambiguously. If one lacks the other chimpanzees, then the message can be deciphered as "stop doing it", "Take on me" or even "Go away."
This study proves that animals and humans have much in common .
