Will life arise naturally? Why dig a pond at random and fish will appear soon after

Lake Eyre is the largest seasonal lake in the world. Sometimes there is lake water, sometimes not. In the rainy season, Lake Eyre is the largest lake in Australia, with an area of ​​tens of thousands of square kilometers. In the dry season, it may be zero, sometimes even for many years. There are no lakes, but no matter how arid the lake bed is, once it encounters abundant rain, it will be fish and shrimps foraged by Australian wading birds, and life will naturally arise? Why dig a pond at random, and fish will appear soon after.

First of all, it is impossible for fish to appear in the pond itself. The emergence and evolution of life is a very long process. There should be prokaryotes first, then eukaryotes, and then multicellular animals. It took a billion years for fish to evolve, and it took a very long time for fish in the ocean to transfer to fresh water on land. Therefore, the pond must have been transferred from the outside through some means. Most fish cannot live without water. How did they cross the land in other water bodies to come to another water body?

brought by other animals. Some aquatic animals, such as cormorants, water striders and frogs, may carry fish eggs to other places as they move through different water bodies, and if the environment is right, the eggs will develop into fish on their own, so that the fish will emerge In a self-contained pond, while a self-contained pond may not be truly isolated, there may be an underground river at the bottom of the pond that connects to other bodies of water so fish can swim through, plus, when there is heavy rain and flooding, the other bodies of water May become integrated with the pond, in which case fish in other waters can easily swim through, otherwise flooding will wash the fish into the pond.

The eggs are very sticky, so when certain birds fish elsewhere, the eggs stick to them, and when the birds fly, the eggs are carried far away. When fish eggs fall, they will hatch into fish when they meet water, maybe we usually look like a former puddle, which is connected to deep groundwater, so some small fish can swim away smoothly, groundwater swims here from another pool , so that eggs are hatched here, and as time goes by, there will be more and more fish here.

Therefore, as long as you dig a hole, you can catch fish. This is the result of many factors such as people, fish, and birds. But in fact, if you observe carefully, you will find that this phenomenon is not very common. Back to the construction industry Topic, in the past, it was necessary to dig a large pit for lime production, as a rule, there would be no fish in such a pit, the reason is that lime water is alkaline, and a high concentration of lime water is not conducive to the survival of fish eggs and the growth of phytoplankton hatching, so it is difficult to form a small ecosystem dependent on algae and zooplankton in lime ponds, and it is also difficult for fish to appear in rice fields where pesticides are usually used.

I believe everyone understands. It is impossible for fish to appear in a newly dug pond for no reason. All creatures in nature have their own set of rules for life. If you want to survive and prosper in the long run, you will explore it. With such unique rules, even with other Plants and living things form a "mutually beneficial symbiosis" relationship that is not harmful to each other, they can help each other survive, and I have to say that many animals in nature are very smart.
