The 10 smartest animals in the world are far more intelligent than you think

Animals rely on intelligence, and smart animals can survive. Below are the top ten smartest animals in the world. What we are worth remembering is that we always thought that the stupid pigs were actually ranked tenth.USA MSNBC The website recently announced the world's top ten smartest animals, chimpanzees, elephants, dolphins, etc. to be selected.

10.Pigs are smart and love clean

Pigs are always covered in sludge and seem to be less hygienic, but some experts point out that they are probably the smartest known to be in captivity and also love cleaner, even more than cats and dogs.Unfortunately, because there are no sweat glands, the pigs roll in the mud to keep their bodies cool.Experiments conducted in the 1990s found evidence that pigs were also very smart.During 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 show that the time they took to complete this task was almost the same as that of chimpanzees, which shows how smart they were.

9.Cats are very adaptable

Like dog owners, some cat owners also train their babies to sit, roll over and drill iron rings.Using positive intensive training with rewards, cats can also master these skills through observation and imitation.Although training a cat is more difficult than a dog, it does not mean that a cat is stupider than a dog.Cat experts say cats are a unique animal that likes to be alone and is 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.

8.Dogs understand similarly to humans

As human best friends, dogs always firmly obey their owner’s orders, but does that mean they are smart?Dogs can learn how to sit, lie down and pick up things, but can they understand their owner’s true intentions?The researchers say dogs are able to find food at least through nonverbal cues.Scientists believe that their understanding may be similar to how humans understand other people’s ideas.In the experiment, dogs were able to correctly distinguish similar photos from landscape photos, that is, they had the ability to form the concept of "dog".

7.Squirrels are also masters of fraud

Will squirrels be conspiracy?Probably.Researchers recently reported that squirrels would make deceptive storage rooms so that possible thieves could not find their own food.During the experiment, after seeing someone steal their peanuts, squirrels' tricks appear more.The researchers said they found evidence that squirrels could understand their peer intentions, although this was only an acquired learning behavior rather than a congenital behavior.Other studies have shown that squirrels can draw a three-dimensional map in their brains, and then recall where the nuts were stored.Of all squirrels, California squirrels are probably the smartest, they will cover up their own scent with the scent of a rattlesnake and use it to protect themselves.

6.A clever crow

Crows are "smart" animals that use twigs, feathers and other debris as tools to trap prey in difficult-to-reach places.A crow named Betty would bend a straight wire into a hook and use it to retrieve the food in the tube.These birds are born with the talent to make tools, and only by observing their elders can they master their skills, which is evidence of high IQ.Research shows that the big crow ( raven） Be proficient in using social influences to get more protection and food.

5.Cephalopod with big head

Are octopus, squid and squid smart?This is a question of scientific interest, but these cephalopods are indeed the smartest invertebrates in the ocean.The brains of cephalopods surround the esophagus, but have some human brain characteristics, such as wrinkled brain lobes and unique areas that process visual and tactile information.

4.The elephant with self-awareness

The absolute size of their minds shows that the elephants must understand the truth.Researchers found that elephants comfort family members, help other animal species in time when needed, play in the water, and communicate with each other by vibrating their feet.Scientists say their biggest gain is that an Asian female elephant named "Happiness" recognizes herself in the mirror.This complex behavior is only experienced by humans, apes and dolphins.

3.Creative dolphin

Australian dolphins use sponges to protect their noses when they look for food at the bottom of the sea.Scientists say this is just an example of the intelligence of dolphins.They make whistles and clicks that may call dolphin names, perhaps the unique language they use to communicate.A famous experiment in the 1960s found that once dolphins realize that they can get rewards from fish by doing novel movements, they will be more creative.

2.A close relative of humans

We humans have intelligence, and chimpanzees must also have certain intelligence, because humans and chimpanzees have 98 genes. ％It's the same.They can make and use tools, hunt in an organized manner, and there are violence among orangutans, etc.Field observations and laboratory studies show that chimpanzees can not only move emotions, but also altruism and self-awareness.Experimental results show that chimpanzees scored higher than humans in many memory tests.

1.The smartest animal is of course human

Scientists may have different opinions on how to define "smart" most appropriately and comprehensively, but they generally agree with the view that humans are very smart high-level animals.But the London Zoo held an exhibition in 2005, which locked volunteers into Monkey Mountain to experience the feeling of animals.Experimental results prove that in that environment, people are not much smarter than monkeys.
