WASHINGTON. Scientists have found that chimpanzees living on the Ivory Coast already use exploratory missions to avoid potentially deadly conflicts with rival groups.
From 2013 to 2016, scientists observed two groups of learning chimpanzees in Africa (Pan troglodytes verus) for eight to 12 hours a day.

Sylvain Lemoine, the main author of the study published in the journal PLOS Biology and an assistant professor in the biological anthropology department at Cambridge University, stated in a statement to the Live Science portal that the boundaries between the territories of chimpanzee groups are not permanent but can change.

The results of the study showed that chimpanzees most often entered the territory of a competing group when its members were located far enough from the entering chimpanzees. At the same time, they indicate that they already can judge the risk-reward ratio, and based on that, they decide whether they will escalate the conflict. The decisive factor is the fact that chimpanzees are currently present on both sides.
“It is possible that we have already observed traces of proto-warfare on a small scale, which apparently existed in true hunter-gatherers,” Lemoine said. He added that even though this behavior was only observed in chimpanzees living on the Ivory Coast, it is likely that it occurs in all chimpanzees because it is evolutionary beneficial to them and helps them survive.
