A new study shows primates have human-like planning skills, based on the information that Dutch researchers have gathered. They began their experiment at the beginning of the year by filming the chimps in the zoo with a drone. The investigation ended on April 10 when the chimps destroyed the camera with tree branches.
Although researchers initially thought their study had been compromised, the analysis of the images has helped scientists draw useful conclusions on primates’ behavior. They believe the attack was carefully planned with human precision and that primates might have acquired a new behavioral conduct.
The video shows how the two female chimpanzees, Tushi and Raime cooperate to take the drone down. Tushi, who appears to be particularly annoyed by the flying object, climbs on a tree and hits the drone with a tree branch. After the second blow took the drone down, chimps gathered around it and threw it multiple times until they were sure that it no longer functioned.
The Dutch researchers played and replayed the tape multiple times because the chimps’ behavior seemed very interesting to them. They were particularly interested in the choices that the two primates made.
Tushi chose a specific tree in the zoo and that tree happened to be the best for the attack. If the female chimp had chosen a different tree, it might not have succeeded in taking the drone down. Similarly, the 6-foot stick that the simian used was the right size for the attack. Smaller branches wouldn’t have had the same effect which means Tushi carefully planned her moves and her strategies.
Jan van Hooff and Bas Lukkenaar, the co-authors of the study, have stated that the grimaces of the simians are incredibly human, too. According to them, the simian was visibly annoyed by the drone; scientists claim they could read the anger on the animal’s face.
Chimpanzees have always trigged scientists’ attention because they have the ability to figure out solutions to provide for themselves. Many discussions have been made in relation to the simians’ ability to break a coconut using two specific rocks.
Researchers think their new study comes to complement this previous assumption and to prove that chimps are capable of logical thinking. Their conclusions were published in the journal Primates.
