After long-term observation of chimpanzees, scientists have noticed a tendency in them to help strangers without a desire for personal comfort, according to the latest research. Such selfless behavior has so far been most often considered a unique human characteristic. Because, according to the common opinion, evolution and natural laws strictly "forbid" a strong male to feed the weaker, let alone help a member of another "competitive" species. To investigate their behavior, the scientists singled out 36 chimpanzees on the Ugandan island of Ngambou. During the first experiment, the monkeys observed a man trying unsuccessfully to reach for a wooden stick that was out of his reach. Frequent repetition created the impression that this stick was extremely important. The reaction of most chimpanzees was very selfless - they would bring a stick to a man, even if they had to climb a tree for it. The chimpanzees could not expect any reward.

But other research has shown that chimpanzees also have some less desirable traits. When feeding, they were generally very selfish and reluctant to share with other members of the group. Monkey selflessness obviously clashes with their selfish motives, which prevail when it comes to feeding. But other animal species are already organizing themselves into societies, fighting and imitating man in "animal" behavior.

Prostitution flourishes in primates

In monkeys, ear plucking is a highly valued activity and serves as a kind of currency. For example, females are willing to provide different types of sexual pleasures for a certain amount of removed ears. Prostitution is a craft older even than humans.

Not even a monkey can be exploited

Monkeys are adamant in seeking the same labor rights. In the experiment, the scientists rewarded two monkeys who worked equally well with different amounts of food. The monkey who got less food started to get angry and after a while stopped working.

Inhuman "war crimes"

Investigating chimpanzees in Uganda, scientists noticed horrific rapes and killings of members of another tribe. Chimpanzees would sneak through the woods like an army and then abruptly attack one of the rival monkeys. The campaign would be over very quickly.

Magpies are more agile than monkeys

Magpies can create, but also teach others how to make tools. They are better at this than most primates. In a recent experiment, two magpies were given two wires. One had a straight wire and the other a curved one. The magpie with the curved wire made it much easier for her to get food. When she became aware that she was unable to reach the food, the flat-wire magpie began to watch her colleague closely and, after thinking, bent the wire. It is important to note that the aforementioned magpies have never been in contact with wires before. During the research, scientists regularly found turned off fire protection in magpie nests. After a while, they found that these intelligent birds do this with ease.

Orcs also learn to hunt birds

At the Canadian amusement park MarineLand, they noticed the unusual behavior of the killer whale there. He chewed a portion of the fish they fed him and began spitting the mixture over the surface of the water so that the bird would come to pick up the offer.

Ants have used pesticides before humans

Even while humans were chasing mammoths, ants were growing suitable food inside the anthills. Some species of ants have a habit of cutting the leaves of plants into pieces and then pulling them into their anthills. There they stack them and grow special types of mushrooms on them that serve as food. If the leaves run out, the ants re-enter the chopped leaves and stack them where needed. In order to protect their mushroom farms, these valuable little creatures have also devised various protection techniques very similar to human pesticide use.
