Orangutans learn how to make brackets in just a few minutes to get hard to reach objects

Orang utans have discovered how to make linked tools from straight wire, in a & # 39; stunning & # 39; behavior that according to experts appeared too late in our own evolutionary timeline.

Researchers have observed this type of tool in orang-utans for the first time, and show how the apes quickly made an instrument with the right shape to reach their treat at the bottom of a vertical tube.

Human children, on the other hand, have a much more difficult time with this task; in previous experiments children from 3 to 5 years of age seldom succeeded, while only about half of the 7-year-olds were successful in their attempts.

The new study was led by a team of cognitive biologists and comparative psychologists from the University of Vienna, the University of St. Andrews, and the University of Veterinary Medicine in Vienna.

We confronted the orangutans with a vertical tube with a reward basket with a handle and a straight piece of wire, said Isabelle Laumer, who led the study at Leipzig Zoo in Germany.

& # 39; In a second task with a horizontal tube that contains a reward in the middle and a piece of wire that is bent 90 degrees.

The retrieval of the reward from the vertical tube required the orangutans to bend a hook in the wire to fish the basket out of the tube.

& # 39; The horizontal tube in turn required the monkeys to detach the bent piece of wire to make it long enough to push the food out of the tube. & # 39;

The researchers discovered that the orangutans quickly figured out what they had to do to complete the task.

Two of the monkeys have even solved the bending and inflexible tasks within the first few minutes.

According to the experts, orangutans seem to perform better than human children. Earlier research showed that children usually know at age 8 how to make hook tools.

However, Orangutans were able to do this with surprising precision.

De The orang utans usually have the hooks bent straight with their teeth and mouths, while holding the rest of the tool straight, & # 39; said Laumer.

& # 39; Then they put it right in the right direction, hooked on the handle and pulled the basket up. & # 39;

Although orangutans are known as intelligent and share 97 percent of their DNA with humans, researchers still say that the latest discovery is a shock.

The study suggests that the monkeys not only use routine behavior, but instead actively come up with a solution to the problem before them, said Alice Auersperg of the University of Veterinary Medicine.

WHO IS SMARTER: CHIMPS OR CHILDREN?

Most children surpass the intelligence levels of chimpanzees before they are four years old.

A study conducted by Australian researchers in June 2017 tested children on foresight, which is said to distinguish humans from animals.

In the experiment, researchers saw a grape drop through the top of a vertical plastic Y-tube.

They then followed the reactions of a child and a chimpanzee to their attempts to grab the grape on the other side before it hit the ground.

Because there were two possible ways in which the grape could leave the pipe, the researchers looked at the strategies the children and chimpanzees used to predict where the grape would go.

The monkeys and the two-year-olds only covered a single hole with their hands when they were tested.

But at the age of four the children had developed to a level where they knew how to predict the outcome.

They covered the holes with both hands and caught what fell through each time.

"Finding this capacity in one of our closest relatives is amazing," added Josep Call from the University of St. Andrews.

& # 39; In the evolution of man, hook tools seem relatively late. Fish hooks and harpoon-like, curved objects only date about 16,000 to 60,000 years.

Although New Caledonian crows use hooks with regularity, there are a few sightings of wild monkeys, such as chimpanzees and orangutans, who previously use detached branches to catch branches out of reach and retrieve them for locomotion in the crown. .

• Such hoisting tools can be one of the earliest and simplest cutters that are used by great apes and our ancestors. & # 39;
