Why Bats Have Become "The King of Poisons"
Longevity, small mammals (such as mice) typically reproduce quickly and die young. The oldest bat species, the bat-eared fox, can live up to 41 years, usually living for 20 or 30 years or more. Despite not equaling the lifespan of most humans, considering their size, these flying creatures have an exceptionally long lifespan, ten times longer than that of similarly sized animals. Bat-eared bats weigh approximately 1/648 of a human and can live for about 20 or 30 years. If scaled to human proportions, their lifespan would be even longer.
The oldest bat species, called Myotis.
Scientists conducted DNA biopsies on animals, marking and releasing them. Researchers subsequently flash-froze some of the DNA samples and dried them with silica gel to observe how chromosomes responded to aging DNA. They found that two bats aged normally like humans. However, two samples from the exceptionally long-lived bat-eared fox lineage showed no signs of aging after this process.
They discovered this surprising force within the telomeres of DNA. Telomeres are like the aglets or plastic caps on the ends of shoelaces: they don't wear down like the rest of the shoelace, but they prevent fraying. As our cells divide, the telomeres typically shorten and are affected by aging.
An expert analyzed why bats are now the predominant hosts for most current viral epidemics.
Dublin University's Emma Teeling explained in a press release: "Bats do not express telomerase and may have evolved a unique process to lengthen their chromosomes without triggering cancer." These exciting new findings, we need to further explore to discover how bats maintain health over time. Scientists are still uncertain how other bat species can survive so long, as only rodents have eternal telomeres. However, they did notice that other bat species express genes that help maintain and repair telomeres. They may gray like the caps on the shoelace ends, but don't deteriorate because of these genes."
The King of Poisons
In recent years, viruses such as SARS (Severe Acute Respiratory Syndrome), MERS (Middle East Respiratory Syndrome), Ebola, and rabies have been the natural hosts of viruses. Why are bats the largest hosts of viruses in nature? To infect a virus, one must not be poisoned first. Bats are in a very special position in the animal kingdom, despite their small size, they have been on Earth for 88 million years, and have evolved over time to become a strong species.
Animal experts say that viruses must first not die and be in a large, populous environment in order to spread the virus. Bats meet these conditions. Secondly, bat body temperature is often maintained at around 40 degrees Celsius, and since viruses are intolerant of high temperatures, bat body temperature indirectly increases their resistance to viruses and reduces the viral load in bats.
In addition to this, bats have a special skill, that is
"DNA repair"Because bats consume a lot of energy every day when flying, to adapt to the rapid metabolism and energy consumption, they have gradually evolved a high degree of DNA repair ability, which gives bats a strong physical level and immune system, so they carry viruses."Rarely develop symptoms""Not develop symptoms"Most bat species live longer than their expected lifespan (highlighted in blue) for their given size. Individual naked rats (marked with a black star)Furthermore, bat feces or fruit they have eaten will indirectly infect other animals, and the virus will mutate during the process and spread to humans. The SARS epidemic was transmitted from bats to raccoon dogs and then to humans. Currently, the intermediate host of the Wuhan pneumonia virus has not been definitively identified.
In conclusion
No buying, no harm, no death, and nature is fair. The cause sown by humans will eventually bear fruit. It is important to fertilize it after planting the cause.
