Look at the stars, they actually look like human beings, and their behaviors are very close to human beings. Just like the chimpanzee in the news found the children's shoes and waved them back. According to research, orangutans can think like humans. Some orangutans have learned to play games and solve math problems. It can be seen that the brain of orangutans can become smarter and smarter through training.
The brain capacity of orangutans is equivalent to the IQ of humans at the age of five. Of course, the IQ of other animals is also very close to that of humans, but orangutans are the closest. Because of this, many zoos will train their minds and do some performances. They can achieve the performance effect not only in IQ but also in behavior.
However, although Xingxin's IQ is very close to human beings, it is not equal to human beings. The development of human intelligence is a continuous process, and it is difficult to determine when it stopped developing. However, research shows that the development of human intelligence has three relatively rapid periods. The first stage is the appearance of babies from 0 to 8 months, the second stage is the period when children are about three years old, and the third stage is the appearance of children around 10 years old.
It can be seen that although the IQ of orangutans is equivalent to the brain of a 5-year-old human. In fact, it only completed the second stage of rapid development. The peak IQ of orangutans is around 5 years old, while that of humans is around 20 years old. Therefore, although orangutans can imitate something, they lack invention and creation.
But orangutans are smarter than other animals. It's not as good as pigs, dogs and pigeons. These animals are all recognized as intelligent animals, and some people think that they are very similar to human monkeys. These animals also have a certain IQ in training, but they are still not smart enough compared with orangutans.
Of course, at first people didn't think orangutans were the closest to human intelligence, but it was generally believed that dogs or monkeys were the closest to human intelligence. The reason for this conclusion is that dogs are the most loyal friends of human beings and have been with human beings for thousands of years. People evolved from apes, so monkeys should have higher IQ.
Obviously, after years of research, these theories have been overthrown. Other animals are only humans. Compared with the IQ of three years old, an orangutan with a brain capacity of five years old is the cleverest and closest to human beings. This conclusion is obtained through long-term observation and research, so it is more authoritative.
Of course, this is also the conclusion of some animals that have already happened. Maybe in the future, new species will be found to be extremely clever, even smarter than writing orangutans. After all, science has been developing.
