A study by Johns Hopkins University concludes that these apes realize when humans do not know information and communicate accordingly

The Bonobos (Bread bread), also known as pigmeo chimpanzees, they are able to intuit the ignorance of others and cooperate to solve a complex situation that is presented to them, a skill that until now was believed exclusive to human beings, according to a new study Posted in the magazine Proceedings of the National Academy of Sciences (Pnas).
The Johns Hopkins University team (USA) came to that conclusion after evaluating the behavior of a group of these Primates To those who put a challenge: find a candy that was hidden inside a glass and using others to mislead, better known as the ball of the ball.
Thus, they tested Nyota (25 years), Kanzi (43) and Teco (13), three bonobos living in Air Initiative, a non -profit organization dedicated to research and education. They were waiting patiently for the human to point out where the treat was. However, when they did not know, they went to their aid.
The apes Not only were they right, but sometimes they point out the cup with effusivity, especially Kanzi, who was very motivated by food. “He repeatedly pointed out in certain phases of the experiment; He gave several taps to get our attention and was quite insistent in it, ”they point out.
“We prejudiced that if the apes really tracked ignorance, when their companions lacked knowledge they would be pointing more often and faster and that was exactly what they did,” says co -author Chris Krupenye.
Ability to cooperate and communicate
In addition, they argue that the results suggest that “apes can simultaneously have two contradictory world visions in their mind”: “They know exactly where the food is and, at the same time, they know that their partner’s vision of the same situation lacks that information ”.
In his opinion, that is one of the most relevant findings: apes are able to cooperate and communicate as humans would in these situations. “This work demonstrates the rich mental bases that humans and other apes share, and suggests that these skills evolved millions of years ago in our common ancestors,” the researchers conclude.
