Bonobos and chimpanzees, the two primate types most closely related to our type in terms of genetic similarity, are only approximately equal to us. They differ by 1.23%. How this great genetic similarity affects the common points in the middle of the types comes up in quite different ways, with different studies that are always being conducted.

A recent study has identified a situation that can be shown as a very adequate example of this situation. In the midst of both bonobos and chimpanzees before starting joint social activities and while ending the activity, it was determined that they greet and said goodbye with mutual glances and various connection signals.

In the study, it was discovered that bonobos in particular have very similar contacts with humans. According to this, the connection that a bonobo establishes when starting a joint activity and ending the actions, with the bonobo opposite. varies according to the degree of proximity.

These behaviors, which are observed before and after many social activities to play games with each other, decrease as the degree of intimacy decreases. ‘courtesy increased and the duration extended’ is taking a turn. Raphaela Heesen, one of the scientists who carried out the research and the lead author of the study, likens it to the connection people have with their close friends, and the situation is ” When with a decent friend, they exhibited shorter entry and exit stages and often did not make contact at the end of the interaction. We know this from our daily life. If we are in contact with a decent friend, we don’t show this kind of courtesy“.

Touching each other, shaking hands and even looking at each other in the middle of the greetings, which is the subject of the word, toe head-to-head. 90% of bonobos and 69% of chimpanzees say ‘hi’ to each other when starting a connection. It is stated that this rate is higher when saying goodbye.
