The secret of nature, as long as a word, such as "when it rains, ants will move", ten, hurry! ! ! !

In some books about knowledge of nature, ants moving, swallows flying low, snake corridors and other phenomena are all considered as precursors of rain. Is that really the case? It can be said that ants can accurately feel that it is going to rain by instinct, and even accurately feel the rainfall. However, ants are a kind of low intelligent creatures, and their visual range is very short. It is a complicated job to measure the relative height between their home and their surroundings mainly by their sense of smell. They must rely on good eyesight and be nearsighted. So ants' eyes are unlikely to be shorter than mice's. As for judging whether your home will be flooded by rain according to the predicted rainfall in the next few days, it is more difficult to judge, and even human beings can hardly do this accurately at present. Are ants more powerful than people and can accurately calculate whether their homes will be flooded by rain? Do you need to move to avoid being flooded by rain? There are ant nests almost everywhere, and there are many near my home. I found that whenever there is continuous rainstorm, the vast land is covered with Wang Yang, and for several days, there is deep rain (relative to ants). Looking around, there are many ants whose homes are completely flooded. So, have the nests of ants soaked in deep water for a few days been destroyed? Not at all. As long as the rain clears and the water recedes, busy ants will soon appear in the holes of those ant nests, but they are busy outside, showing no signs of heavy casualties. This shows that the ant's nest is not afraid of short-term rain immersion. When there is no air in the upper part of the nest because of rain, the ants in the nest can block the passage and move to the lower part of the nest to avoid the damage caused by rain. The hydrophobic effect of soil and the structural characteristics of the nest deeper make it unnecessary for ants to start thinking about whether to move as soon as they feel it is going to rain. In order to verify whether the ants in the completely submerged ant nest will be drowned by water, it can also be verified by flooding experiments. The experiment shows that after being flooded for 4 hours, it has no effect on the life of ants in the nest. Since the ants in the flooded nest will not be drowned by water, in the process of biological evolution, there is no need for ants to evolve the instinct of choosing to move before it rains. The choice of biological evolution is often the most scientific choice. In order to prevent the ant nest from being flooded, a more scientific choice should be to build it in a waterproof and flooded place at the beginning of construction, instead of taking the move action of "wasting people and money" again and again. Didn't ants obey the evolutionary choice when they built their nests? From this point of view, ants moving is not necessarily an action taken by ants worried that their homes will be flooded. It is entirely possible that there are other reasons. For example, due to the increase in the number of ant colonies, there is a shortage of food near the ant nest, and it is necessary to find new food sources. Because other ant colonies near the ant nest pose a threat and need to avoid danger, or each group of ants has the habit of building multiple ant nests. As for ants choosing to move on cloudy days or at night, the main reason is to prevent the harm that sunlight may cause to ant eggs. Because people don't pay attention to the actions of ants at night, they can often see ants moving on cloudy days, so they associate ant movement with rain. !
