An earthworm is broken into two, which one is its consciousness?

I believe many people have heard this saying: place earthworms upright, then cut them horizontally into two parts, then one earthworm will become two. On this basis, some people have raised new questions: Originally, an earthworm only had one consciousness, so after it was broken into two earthworms, did the consciousness also split into two? Answer: If an earthworm breaks into two, at most only one will survive, and the earthworm itself does not have thinking consciousness.

If an earthworm breaks into two, not both will survive. First of all, earthworms do have the ability to regenerate, but individual differences are obvious. The regeneration ability of Earthworm Luzheng is very poor, and it is difficult for the severed parts to grow back. The regeneration ability of Earthworm ringworm is very strong, and most organs can be regenerated. In order to study the regeneration mechanism of earthworms, there was an experiment abroad. Each part of the earthworm's body was cut off, and then the regeneration status was observed. Finally, the conclusion was found: whether the earthworm can regenerate depends on the reproductive ring, and the focus is not on the brain. Take an earthworm composed of 150 links as an example. If the 1-10 links of the head are cut off, the remaining body will grow another head; if the 41-150 links of the middle and rear parts are cut off, the remaining body will be The lower front half of the body will then grow into the middle and tail. However, the regenerated length will be shorter than the original length, which is affected by its own factors and external conditions. The special situation is: if the incision position of the knife is at the 11th-40th link, it will be difficult for the earthworms to regenerate, and they are likely to die, because the important organs of the earthworms are at this position. Some people may have questions, if the 41st-150th link is cut off, can the cut part still regenerate? Can he still live? The answer is: no.

Biologists have discovered that the 11th to 40th segments of earthworms contain reproductive rings. The function of this structure is to reproduce offspring. Only earthworm bodies containing this structure can regenerate. We often see that the tail of an earthworm has been cut off, and the tail can still jump around for a while, making people mistakenly think that it can continue to live and become an independent earthworm. This is actually wrong. The tail can move because the undead lower-level nerve cells in the earthworm's tail respond to external stimuli. People with life experience should know that freshly slaughtered beef cut into large pieces will sometimes beat like a heart. This is caused by the fact that the nerve endings have not died. It is the same reason. After the tail moves for a period of time, it will die, so the earthworm is cut into two parts, and only one part may survive.

Earthworms have no thinking consciousness. They are lower organisms. Their brains are very small and simple. They cannot even control muscle activities. They can only guide earthworms to move and process some simple physiological activities through the perception of light. , even memory is stored in the ganglia of the pharynx and abdomen. Earthworms have no consciousness and cannot carry out thinking activities (simple memory does not belong to thinking), and their reflexes to external stimuli also rely on ganglia, which are all instinctive reactions. Even if the earthworm's brain is removed, it will not pose a threat to its life. This is very different from the human brain.
