Bonobos are aware of their actions and behaviors

Bonobo immediately helps the signs of being able to guess the mental state of others who do not know what they know.

Ability to think about what others are thinking, Heart theoryThis is an important skill to make humans navigate the world of society. It can recognize that someone holds different beliefs and perspectives for ourselves and support the ability to fully understand and support others.

The question of whether our closest living parent, Relative, has the theory of heart has been discussed for decades. Somehow Mixed resultNon -humans, a great ape seem to have some aspects of this ability, suggesting that it is evolved in older than once considered. For example, a wild chimpanzee that is fake but sees nearby snakes Alert group member They know they haven’t seen it yet.

However, he says that he has missed the clear evidence from the controlled settings that the primates can track different perspectives and act based on them. Luke Town Row At Johns Hopkins University in Maryland.

To investigate this, with Townload Christopher CrupenierAt Johns Hopkins University, three male Bonobos at the APE Initia Chib Research Center in Iowa will identify the ignorance of the people who are trying to cooperate and show them to them to solve the task. I tested.

The table between Bonobo and the experiments had three upward plastic cups. The second researcher put a barrier between the experiments and the cup, and hid a snack like a juicy grape under one of them.

In one version of the experiment, “Knowledge Conditions”, the experiments were able to see where the treatment was placed in the barrier window. In the “ignorant state”, their views were completely blocked. When the experimental finds food, they give it to Bonobo and provide the motivation for the apes to share what they know.

TOWNROW and KRUPENYE examined whether the apes were pointing to the cup, and how sharp they were after the barriers were removed 24 times under each condition.

On average, they discovered that Bonobo had a less time to point in 1.5 seconds, and was pointed out in about 20 % of the exams in ignorance. “This indicates that you can actually take action when you realize that someone has a different perspective,” Krupenye says. He added that BONOBOS seems to understand the characteristics of other people who believe that researchers do not understand historically.

This simple but powerful research is experimentally supported by the results of an existing survey from wild apes. Zanna Clay At Darlam University in Britain. However, she warns that research animals have been raised in a human -oriented environment, and the survey results may not be applied to all bonovos. However, she added that it does not impair the result of the capacity.

Certainly, finding this ability with these three bonovos indicates that the potential exists in their biology, and may be the same for our common ancestors. It indicates that it is expensive, says Kurpenier.

“Our ancient human parent Relative also has these abilities and suggests that they can use them to strengthen their cooperation and coordination.” Laura Lewis At California University Berkeley. “By understanding that someone is ignorant, our ancestors use these abilities to communicate more effectively with social partners, especially for evolutionary information, such as food places. , I was able to adjust.
