This adorable animal you see in the image is a Galago, also known as a “bush baby” because its call sounds very similar to a baby's cry.

It lives in the forests of sub-Saharan Africa and usually uses the inside of tree trunks as a burrow, since it feels safe there, but, in a forest in Senegal, a group of hunters has devised a rather brutal system to kill them: they sharpen the tip of narrow sticks like a spear and insert them suddenly inside the hollow trunks, in the hope of piercing a sleeping galago.

Then they extract the stick and look at its tip: if it is bloody, they know they have found a new prey. Does this seem like a cruel hunting style to you? possibly, but what if we told you that those hunters with their small spears are not human? They are actually chimpanzees.

A team of researchers led by anthropologist Jill Pruetz, from Iowa State University, published a study in 2015 in the journal Royal Society Open Science in which they claimed to have seen a group of chimpanzees use this hunting technique more than 300 times. Apparently, the apes make their weapons by sharpening sticks of about 75 centimeters with their teeth and they learn the technique from each other.

Females are more likely to hunt with weapons than males. regardless of how interesting the study may be from a biological, evolutionary or even social point of view.

One could hardly blame chimpanzees for their behavior, given that they are animals: they want to eat and use all their abilities, including making tools, to capture their prey, without ever considering whether what they are doing is right or wrong, whether they are cruel or evil for cutting through defenseless and harmless creatures while they sleep curled up in their burrows.

They have the intelligence necessary to make spears and learn hunting techniques, yes, but they lack morality, the concepts of good and evil are exclusively human. What do you think of this behavior?
