Analysis:

Do animals have "mathematical minds"? What's the difference between the "mathematical level" of different animals? This is an important topic that scientists all over the world have been trying to explore for a long time.

Studies have confirmed that many animals are counted. Dr. Hansel, an animal psychologist at Harvard University in the United States, first gave animals the wrong information in the experiment, and then observed their reactions. He once distributed two bananas to 100 Caribbean wild monkeys every day for a month, and then suddenly it was reduced to 1 banana. At this time, 96% of the monkeys watched banana 1 twice, and a few even expressed their dissatisfaction by screaming. Gordan, an American animal behavior researcher, did a similar experiment. He first asked his eight chimpanzees to eat 10 bananas at a time, and so on many times. One day, he suddenly gave each orangutan only eight bananas. As a result, all orangutans refused to go away until the owner compensated. It can be seen that both wild monkeys and chimpanzees have "mathematical minds".

There are still differences in the counting ability of animals. Someone once put three small plates in front of Feng Tou McKee. One plate contained 1 bug, one plate contained two bugs, and the other plate contained three results. Sometimes it eats two plates first, and sometimes it eats three plates first. According to this experiment, curassow knows that 2 is more than Wei, but he can only count to 2. Scientists once put four identical boxes in front of pigeons, and the covers of the four boxes were painted with 1 minute, 2 minutes, 3 minutes and 4 minutes respectively. Harvard knew in advance that there was food in the quarter box, so it always opened the quarter box first. It can be seen that pigeons can count to 4. Haenszel, an animal psychologist at Harvard University, also trained a parrot with mathematics. Finally, he can accurately report the number of colored building blocks on the tray in English, but the number of building blocks cannot exceed six. Psychologists from Columbia University in the United States have conducted many experiments on two monkeys, and found that monkeys can point out numbered icons from small to large on the TV screen and count to 9. Scientists point out that apes are the cleverest in the animal kingdom. About 70% of adult apes can count from 1 to 100 after training, and the accuracy rate is over 90%.

We can also appreciate the mathematical talents of many animals from nature, some of which are really impressive. If you want to say that the real "mathematical genius" in the animal kingdom, I am afraid it must belong to bees. Not long ago, two German entomologists discovered through experiments that bees can not only count, but also judge the position and direction according to the ground marks and their order. The two scientists trained bees to look for syrup in a feed tank containing syrup 250 meters away from the hive. The experiment was carried out on a large flat grassland, where there were no obvious directional marks. The experimenter placed four tall tents on the line from the beehive to the slurry feed trough, with the distance between adjacent tents being 75 meters, and a trough filled with concentrated feed was placed between the third and fourth tents. It turns out that most bees still fly to the feed trough next to the fourth tent far from the hive. After that, the two scientists changed the number and spacing of tents and feed troughs, and found that the number of tents played a major role in the process of bees looking for syrup. They obviously took the tent as a direction sign. It can be seen that when bees collect nectar in nature, they will remember the number of natural fixed signs such as trees, bushes and flower beds around the hive.

Every morning, when the sun rises to the horizon, the reconnaissance bees in the bees fly out to spy on the honey source, and report the quantity, distance and quantity of nectar with their unique "dance language" when they come back. So the queen bee sent worker bees to collect honey. Surprisingly, their "fuzzy mathematics" is quite accurate, and there are not many worker bees sent out, just enough to make honey. In addition, the hive built by worker bees is also very wonderful. It is a strictly hexagonal cylinder with a hexagonal opening at one end and a closed hexagonal cone bottom at the other end, which consists of three identical diamonds. 1at the beginning of the 8th century, the French mathematician 2 malachi once measured the dimensions of beehives, and found that all obtuse angles of the diamond-shaped chassis were 10908, and all acute angles were 70032. Later, after French mathematicians Koenig and Su Gexing? Economist Mark Lorraine calculated theoretically. If you want to consume the least raw materials and make the largest diamond container, it should be from this angle. So bees are worthy of being "gifted mathematicians and teachers".

For a long time, scientists have always believed that only human beings have the concept of numbers and the ability to calculate. The above experiments are undoubtedly of great significance to our understanding of animal intelligence.
