Corona can rain havoc for many years, destroying humans even 20,000 years ago; Evidence was found in the DNA of the people of East Asia

 Corona can rain havoc for many years, destroying humans even 20,000 years ago; Evidence was found in the DNA of the people of East Asia

If the coronavirus is not controlled soon by vaccination, it will spread for many years. According to research published in the science journal Current Biology, Corona has been raging in East Asia for almost 20,000 years. Research has shown that the ancient coronavirus was rampant in the area for many years. According to David Enard, an evolutionary biologist at the University of Arizona who led the research, we should be concerned. What is going on now could last for many generations.

The rage was so great that the gene was affected

The outrage was so great that even today its remains are found in the DNA of people living in China, Japan, Vietnam, and East Asia and surrounding areas. Evidence of coronavirus mutation has been found in 42 genes of the population living in the area. In scientific parlance this is called genetic adaptation. Coronavirus (SARS-COV-2) has so far killed more than 180 million people worldwide and killed more than 3.9 million. The world has lost billions of dollars so far. Millions of people have become poor again. Researchers say that if the coronavirus is not stopped by rapid vaccination, the epidemic will continue for many years and the situation will worsen.

Along with viruses, human genes also mutate

Just as viruses mutate in order to protect themselves, so do human mutations. That is, the virus has been altering human genes for generations.

A mutation in a gene against a virus can cause a gap between life and death. This change is also passed on to future generations.

Such a mutation can cause the human immune system to isolate a virus's protein from it, that is, to kill it.

Viruses, on the other hand, also modify themselves. It reshapes its own proteins to protect the immune system. In response, the immune system can also mutate its own genes.

Dr. David Enard and his colleagues have seen this pattern of change in the human genome recur over the years.

Comparison of 2500 DNA with 26 types of population

When the corona spread, he wondered if an old coronavirus had left its mark on the human genome. To find out, he and his colleagues compared the DNA of more than 2,500 people from 26 different populations around the world.

Evidence of coronavirus exposure was found in 42 genes in five space populations. This is called adaptation. This adaptation to the gene was found only in the East Asian population. No such indication was found in the rest of the world's population.

Researchers believe that this mutation against the virus in this gene may have occurred 20,000 to 25,000 years ago.

The genes associated with specific lung proteins were modified

A virus is a biological structure that, instead of reproducing like other organisms, attacks the cells of other organisms and makes more and more copies of itself using its genetic material. The virus interacts with and binds to specific proteins derived from human cells, which we call viral interacting proteins (VIPs).

Recent research has found traces of mutations in 42 genes to prevent coronavirus, all of which are related to the viral interacting protein (VIP) found in the lungs. That is, human genes modified these proteins to survive coronavirus.

Researchers did not know the ancient history of Corona

Researchers have not yet been able to determine the ancient history of the coronavirus family. In the last 20 years alone, the three corona viruses have transmitted to humans and caused major changes (adaptation) to cause serious respiratory illness. The viruses are covid-19, SARS and MERS.

Three viruses have wreaked havoc in the 20th century

According to Yasin Souilmi and Ray Tabler, a postdoctoral researcher at the University of Adelaide in Australia and co-author of the research, the history of the virus is older than human culture. In the 20th century, three types of influenza viruses - Spanish flu (1918-20), Asian flu (1957-58), and Hong Kong flu (1968-69) have killed millions. Many genetic markers remain in the body of this epidemic.

Finding a cure for coronavirus will also help

According to Yasin Souilmi, a scientist looking for a cure for the current coronavirus wants to study these 42 genes. This will show you how to develop resistance to the current coronavirus.
