The smartest animals on earth are not only human beings, but also many animals who have their own ideas and wisdom. Today, Xiaobian will take stock of the most intelligent animals in the world. Let's take a look at all the animals.
1. Smart Figaro
Scientists at the University of Oxford in the UK have discovered unexpectedly that a cockatoo named 'Figaro' can make and use tools and eat food through self-made tools. According to biologists, such a phenomenon is rare.
According to a video taken by researchers at Oxford University, the parrot 'Figaro' saw a nut placed by researchers outside the cage and tried to reach it. To the surprise of the researchers, 'Figaro' picked up the branch in the cage, clawed it out with his jaws and bit off all the branches, so that the smooth stick could reach out the gap between the cages. Figaro pulled the nut close to the cage with a homemade stick and successfully ate the nut. Researchers say it's amazing that Figaro can use tools, and it's even more surprising that he can make tools himself.
2. Chimpanzees, close relatives of humans
Chimpanzee is one of the most representative animals. Animal researchers are not only concerned about them because they are inextricably linked with human beings; what's more interesting is that with the deepening of research and more and more facts revealed, people are surprised to find that their IQ is much higher than people's imagination.
3. Elephants with self-awareness
The absolute size of their brains shows that elephants must understand. The researchers found that elephants comfort family members, help other animal species when needed, play in the water, and communicate with each other by shaking their feet. Scientists say their biggest achievement is that an Asian female elephant named 'happiness' recognized herself in the mirror. Only humans, apes and dolphins have this complex behavior.
4. Cephalopods with large heads
Is octopus, squid and squid smart? It's a question of scientific interest, but these cephalopods are indeed the smartest invertebrates in the ocean. The brain of cephalopods surrounds the esophagus, but it has some characteristics of human brain, such as wrinkled brain lobes and unique areas for processing visual and tactile information.
5. A clever crow
Crows are 'handy' animals that use twigs, feathers and other debris as tools to trap prey in hard to reach places. A crow named Betty would bend a straight wire into a hook and use it to get back the food in the pipe. These birds are born with the gift of making tools. It is only through observing their elders that they can master their skills, which is the evidence of high IQ. Research shows that ravens are adept at using social influences to get more protection and food.
6. Squirrels are masters of deception
Can squirrels play tricks? Maybe. Researchers recently reported that squirrels make elaborate, deceptive storerooms so that potential thieves can't find their own food. In the course of the experiment, the squirrel's deception will appear more after seeing someone steal their peanuts. The researchers say they have found evidence that squirrels can understand their peers' intentions, although it's an acquired behavior rather than an innate one. Other studies have shown that squirrels can draw a three-dimensional map of the brain and recall where nuts are stored. Of all squirrels, California squirrels are probably the smartest, using the scent of rattlesnakes to mask their scent and protect themselves.
7. Dogs understand in a similar way to people
As the best friend of human beings, dogs always obey their master's orders firmly, but does this show that they are very smart? Dogs can learn to sit down, lie down and take things, but can they understand their master's real intention? According to the researchers, dogs can at least find food through non-verbal lines. Scientists believe that they may be understood in a similar way to humans. In the experiment, dogs were able to distinguish between similar photos and landscape photos, that is, they were able to form the concept of 'dog'.
8. Cats have strong adaptability
Like dog owners, some cat owners train their babies to sit down, turn over and drill into hoops. With rewarding positive reinforcement training, cats can also master these skills through observation and imitation. Although it's more difficult to train a cat than a dog, it doesn't mean that a cat is more stupid than a dog. Cat experts say that cats are different animals. They like to be alone and driven by survival needs. This allows them to adapt to a large number of different captive environments for at least 9500 years, even their crowns.
9. Pigs are smart and clean
Pigs are always covered in mud and seem to be unsanitary, but some experts point out that they may be the smartest and cleanest of the known captive animals, even more than cats and dogs. Unfortunately, without sweat glands, pigs roll in the mud to keep them cool. Experiments in the 1990s found evidence that pigs are also smart. In the experiment, pigs were trained by researchers to move the pointer on the screen with their mouths and use the pointer to find the graffiti they saw for the first time. The results showed that they took almost as long to complete the task as chimpanzees, so the intelligence level was obvious.
10. Of course, the most intelligent animal is human
Scientists may disagree on how to define 'intelligence' in the most appropriate and comprehensive way, but they generally agree that human beings are very intelligent advanced animals. But the London Zoo held an exhibition in 2005, which put volunteers in monkey mountain to experience the feeling of animals. Experimental results show that in that environment, people are not much smarter than monkeys.
