Pigs, pigs and pigs are the smartest domesticated animals on our planet. Although the primitive intelligence of pigs may be similar to that of cats and dogs, the ability of pigs to solve problems far exceeds them. In an experiment in the 1990s, scientists found that pigs could move the cursor on the screen like chimpanzees and distinguish the order in which graffiti appeared on the screen.
In addition, pigs can quickly understand the principle of mirrors, and they can determine the food around them by reflecting images. But whether pigs have self-awareness, that is, whether pigs can confirm that the image in the mirror is themselves, is still uncertain.
Octopus is the cleverest invertebrate. Octopus shows long-term memory and short-term memory in maze and problem-solving experiments. Octopus can open the jar, squeeze the hole and jump from one cage to another to eat snacks. After training, octopus can also distinguish different patterns and shapes. Octopus is the only invertebrate that has been proved to be able to use tools. It has high intelligence. They will repeatedly take out the bottles and toys in the aquarium and then pick them up to play. Moreover, they will reassemble the discarded coconut shells as their own shelter.
Crow In many Western European myths, crows often play the role of shrewd liars. Actually, crows are really smart. For example, crows can use tools and hide and store food. But crows are the cleverest, because they have memories of scenes and can predict the future based on personal experience.
Some people have seen crows throw nuts on the road and let cars run over them. Some crows even found a way to use poisonous toads, using tools to deal with the poisonous parts of toads.
Moreover, crows have a strong revenge, have the ability to recognize faces, and can remember a person's face for many years. So don't offend crows.
Dolphins are in the ocean. Dolphins have always been regarded as very friendly and intelligent mammals, and even help people who fall into the sea. They live a very United social life in the ocean. We now think that dolphins have their own complex language. Moreover, they can also learn a series of very complex behavior activities under the guidance of human coaches by using the environment in the ocean. Dolphins have their own views on many things. Like primates, dolphins have "self-awareness" and show super intelligence.
When bottlenose dolphins are foraging in the ocean, they will find sponges wrapped around their noses in case they are injured in the process of finding food.
elephant
The society in which elephants live has a complex social hierarchy, and elephants will take the initiative to help other animals. Elephants have few natural enemies in the animal kingdom, and even tigers and lions will give up three points. Pregnant females know how to induce labor by eating special leaves. They have strong social adaptability and will throw stones at the electric fence to destroy it and cut off the electricity. Excellent problem solving skills.
In addition, the cooperation level of elephants can be comparable to that of gorillas, and partners can coordinate to complete a required task and get rewards. But what makes elephants different from other animals is their death ceremony. Elephants will visit graves and check the condition of dead elephants with their noses and feet.
Summary:
Although human beings have the highest intelligence on the earth, primates follow closely, there are actually many animals with high IQ. They have strong systematic thinking and problem-solving ability, and even some animals can use tools to solve difficult problems. Although we often use "pig" to express our praise, pigs have very strong systematic thinking ability and may even have self-awareness; Octopus, the only invertebrate that can use tools, can please itself with toys; Crow, strong memory and face recognition ability; Dolphin, with strong teamwork ability and learning ability; Elephants have a unique sense of death and social adaptability.
