These animals have human intelligence

With great intelligence, many animals know how to use tools to get food, cook food or add spices to food.

>>>10 most intelligent animals

The animals below have great intelligence:

African gray parrots deduce like humans

African gray parrots have the ability to deduce finding places to hide food, only humans and monkeys can do, a study said: "It selects exactly 23 of the 30 trials. Until now, only monkeys have been able to carry out this problem, but in easier experiments, and using insights , " said Sandra Mikolasch.

Orangutans learn how to use TB to catch fish

Scientific research shows that orangutans have considerable strength when they can lift their weight more than 10 times their body weight. Not only that, they are also one of the smartest primates with the ability to use sophisticated tools.

The most obvious demonstration of the ability to use the tool is the capture of fish with TB. In 2008, staff in the animal sanctuary on Kaja Island in Borneo witnessed the orangutans hanging from tree branches for tuberculosis to catch fish, as the locals do there.

Probably the orangutans have observed and found us to use tools to injure other species. They quickly followed, calmly using sharp blades to finish off their prey.

However, it is fortunate for humans. Physical evolution cannot satisfy the orangutan's desire. It is the lack of ingenuity that makes them almost unable to catch any fish. But they were able to practice using sticks to poke fruit on branches and fall to the ground.

Dolphins use sponges as masks

Dolphins or bottlenose dolphins are very intelligent and friendly humans. We are so used to the images of dolphins performing circus in swimming pools but have you met any dolphins who know how to use sponges to make masks?

Because often sniffing the seabed to find food, sometimes the dolphin is often attacked by a few sea creatures by poisonous spines, typically demon face fish.

Therefore, the Gulf of Shark dolphins in Australia know how to remove the sponge and "wear" in front of the nose like a protective mask.

Scientists first noticed this phenomenon in 2005, but some studies have shown that dolphins use foam as masks for 180 years ago.

Now, more than half of the Bay dolphins Sharks know how to use sponges to feed, the rest use other masks similar to sponges.

Japanese monkey species spice up food and play snowballs

Humans are probably the only species to eat according to taste, not the amount of nutrients needed. Most other animals will put all the food in their mouths, as long as it doesn't kill them.

However, the short-tailed monkey species in Japan is not so conceived. The incident began in 1953, when researchers threw sweet potato monkeys for the purpose of exploring their behavior.

During the experiment, Imo - the name of a monkey placed by researchers, washed food in saltwater with the intention of removing sand.

But then, Imo realized that soaking sweet potatoes in salt water would make salt soaked in potatoes and tastes better than before. Imo was excited and howled and shouted at all of his fellow men there, immediately afterwards, all the monkeys were salted with potatoes to eat.

Not only that, Imo and his companions can also spend their time playing snowballs - a favorite game for many in the winter.

Ants count the steps when moving

Scientists have long wondered how ants can find their way home so well that they have virtually no brains and nests are identical.

Some argue that ants rely on visual cues, but experiments show that blindfolded ants are also capable of navigating no less than normal ones, so this hypothesis is quickly eliminated.

Several years ago, the scientists examined another hypothesis. Through the 'biological body measuring the distance', ants count their moves to a certain location.

Just like blind people remember the layout in the house by remembering the number of steps when going from room to room, ants will remember the number of steps they move starting from the nest until they meet the "goal".

Scientists tested this hypothesis. First, they train ants in a straight line by placing food 9m away from them. Then they discarded the food, ants still moving in the right direction that they still went until they realized there was no food there, they began to move indefinitely around to search for candy or carcasses. object.

This proves that it is possible to orient the position of the food that is being directed, but it is not enough to confirm that the ant is capable of counting steps.

Scientists continue to do some small experiments. Some ants have their legs cut short to narrow their strides; others were added to extend the stride. The ants cut their feet enough steps and stopped before reaching the target's position. The ants with stilts also took enough steps but because of the longer stride, they had overcome the position of food without stopping.

After being familiar with his new stride, ants began to orient themselves to the food position and moved more accurately. This proves that the hypothesis is correct.

Kanzi chimpanzees can cook their own food

Few doubts, not only people who know how to cook and make delicious meals, Kanzi chimpanzee can do the same.

Kanzi chimpanzees living in a charity reserve in Iowa (Congo) belonging to the dwarf chimp Bonobo can cook their own food on the self-built campfire. The wooden bars were carefully collected by Kanzi everywhere about piling up, not merely whirling around.

Not only that, Kanzi also knew how to self-fire, cooked food to the right level. Interestingly, Kanzi was not taught by anyone but taught himself.

After observing the humans for hundreds of times, he imitated them. Now, Kanzi is teaching his son Teco and perhaps this skill will be passed on to many generations of chimpanzees.

Seals of food

Soc knows how to create fake food hiding places to trick thieves. This behavior manifests itself after they observe humans stealing their chestnuts. Rodents also know how to create 3-dimensional maps to recall where they hide their food.
