When it comes to salamanders, I believe many friends will think of geckos. For no other reason, the two creatures are so similar that many people are stupid and confused. But in fact, there is no resemblance between salamanders and geckos. Because salamanders are amphibians.
Whereas, geckos are reptiles. In addition to this, salamanders mostly stay in the water, while geckos never go into the water and tend to live only on land. Those who are familiar with salamanders will often know the name four-legged fish. Unfamiliar people may confuse salamanders with geckos.
In this way, it is not surprising that the silly is not clear. It is worth mentioning that salamanders are one of the surviving species from the same period as the dinosaurs. This means that the salamander is a very old living creature. It is mainly found in the temperate regions of the northern hemisphere.
Not only that, but salamanders are also very similar to reptilian lizards. That is, both have four legs, and both can appear to crawl on the ground. However, the salamander's body has distinct markings or cockscomb-like protrusions, which is the key to distinguishing a salamander from a lizard.
Salamanders prefer to live in areas with a lot of water, such as swamps, shallow puddles, ponds, and rice paddies. However, many salamanders can only be seen in an environment with low temperatures and clean water. It is rare to see it in areas with high levels of environmental pollution.
In the salamander, it also has a god-level ability, that is, the ability to regenerate. This means that when the salamander is too badly damaged, its tissues begin a process of regeneration and can be replicated almost completely. So can axolotls live forever?
The answer is clearly no. Because the ability to regenerate is only a reorganization of the structure of the cell, it does not mean that the brain mechanism can hinder the debuff process over time. In other words, the regenerative power of an axolotl is like a young limb paired with an old brain.
In this way, even if the limbs are still sound and fast, the brain has long been unable to keep up. The process of giving orders will undoubtedly be greatly affected. Substituting this assumption into human beings, even though humans can replicate equally proportional well-developed limbs.
But brain aging is inevitable. In this way, humanity will eventually have to face death. It is not possible to successfully escape death and then gain eternal life. Researchers have also studied other animals when studying the regenerative ability of salamanders.
As for why salamanders have the ability to regenerate, researchers have found an immune cell. In other words, if the macrophages no longer exist. The salamander then loses this ability to regenerate.
When it comes to immortality, I believe that many friends will immediately think of Tang monk meat in "Journey to the West". In fact, the statement of Tang monk meat is just a lie. The reason is that Tang Seng did not have the news that his flesh could live forever in the early days of learning scriptures.
In other words, the news was deliberately released. It's to lure some indigenous monsters to join in this big show. The audience is the Buddha, the Tao and the Heavenly Court, and the singers are naturally Tang monks and apprentices on the bright side and fighting in the dark.
Moreover, there is no record of a truly immortal person in human history to this day. This means that human beings will not be able to escape the cycle of life and death in the end. All people will eventually have to face death. And if you want to live forever, you first need to resist the erosion of time.
The erosion of time here is actually very obvious. That is to say, if people's various body organs can always be in peak condition, then it is equivalent to being in a state of immortality. The second is to get out of the process of life and death.
In particular, you can't face death head-on. In the current state, it is obviously difficult to stand. Finally, the human life span can only be achieved by breaking the influence of various factors. In other words, even if it will still be greatly affected, it must be in a state that extends indefinitely.
Translating the concept of immortality to the salamander's ability to regenerate reveals that the salamander does not meet all three conditions. First, the reproductive state of salamanders has not yet escaped the category of the cycle of birth and death. In other words, the salamander has the ability to regenerate.
But eventually he will die. The axolotls we see now are not the same as those that were alive in ancient times and in the age of dinosaurs. Second, the regenerative ability of salamanders depends on the power of macrophages. In other words, you can't do it without it.
Of course, we can't ignore the fact that the regenerative ability of the salamander is mainly used for the regeneration of its limbs. This shows that it is still possible for axolotls to be brain dead. If the axolotl's brain structure is destroyed, the ability to regenerate limbs cannot be activated.
If the axolotl's brain is under age, the rate at which the ability to regenerate limbs may also be reduced. The meaning of immortality at least refers to the fact that the various body organs are not in a state of significant aging, especially the part of the brain.
The third is that the lifespan of salamanders is not very long. At least compared to the contemporaneous turtles, there is no advantage. What's more, there is an inherent recognition of the long life span of soft-shelled turtles in my country's folk sayings: the thousand-year-old king of eighty-thousand-year-old soft-shelled turtles.
To sum up, although the salamander has the ability to regenerate, it cannot be described as immortal. Because salamanders do not occupy a considerable degree of dominance either in terms of complete organ replication or longevity. Not to mention jumping into the cycle of life and death.
