In the present century, mankind is facing many challenges, for example, environmental pollution, terrorism, proliferation of nuclear weapons, etc. However, it is unlikely that some people will believe that the world will be hit by a global epidemic by the turn of the century. We know this epidemic as Covid-19, which is caused by a virus called SARS-Cov-2. Nothing can be said definitively about the onset of the epidemic, but the evidence suggests that it began in late November or early December last year and then within six months of the outbreak of the virus (SARS). -Cov-2) Spread all over the world. According to statistics so far, about seven million people in the world have been infected with the virus and the resulting death toll is more than four million.SARS-CoV-2 origin, assumptions and reality,Sars Vs Covid 19, facts about sars,info about sars, composition and structure of sars, transmission of sars.

| SARS-CoV-2 origin, assumptions and reality |
Due to the initial lack of information and the scientific complexities of recent research, the majority of the public, ignorant of scientific science and logic, remained unaware of the nature of the virus and its epidemic, creating a scientific and conscious vacuum. Done. Which was filled with various conspiracy theories. The misuse of scientific terms and the eloquence and rhetoric of words make many of these theories superficially acceptable. In comparison, the scientific facts about viruses and their epidemics are relatively complex, requiring advanced biological knowledge to be understood. As a result, a large majority of the people favored his conspiracy theories. Probably a big hypothesis in these theories is about the origin of SARS-Cov-2, according to which the virus was deliberately created in a laboratory, so that some countries or individuals could achieve certain nefarious purposes.

Recent research on SARS-Cov-2 completely refutes this assumption and provides clear evidence that it did not match. However, the six major viruses found in its spike protein have evolved as a result of natural evolution. But to understand this evidence, it is necessary to know some basic biological information. Therefore, in order to understand the origin of SARS-Cov-2, one must first examine its structure.
The SARS-Cov-2 virus is so small that it cannot be seen even with a normal microscope and requires a special microscope called an electron microscope. Structurally, the virus is circular in shape and its shell is made up of proteins. Inside this protein is its genetic material RNA, while on top of the protein there are thorny structures. Called spikes, just as all the information that runs on our computers and mobiles is contained in their software in the form of codes, so all the information about the structure of the virus and its ability to cause disease is contained in its genetic material. Is present in the RNA. This RNA determines what the shell of the virus will look like and what its spike will look like. In total, this information is contained in the RNA of the virus in the form of about 30,000 codes.

Recent scientific research has shown that the genetic material of human SARS-Cov-2 is 96% identical to the genetic material of a virus found in a particular type of bat (Rhino lophus). However, when the genetic material of humans and bats was compared only to the part that makes the spike protein, it was found that the two viruses are very different from each other. It is important to note that the spike protein on the virus determines which organisms the virus may be attacking. Spike protein itself is a large molecule made up of more than a thousand small molecules. Some of these smaller molecules determine the ability of viruses to attack different organisms, as these six molecules are different from viruses found in bats and humans. Therefore, it is safe to say that the virus was not transmitted directly from bats to humans.
SARS-Cov-1, a virus similar to SARS-Cov-2, caused a limited outbreak in humans in 2003. When these six molecules of the spike protein of viruses were compared in those days, only one molecule was found to be identical, while those six molecules in the five differently found spike proteins were found to be similar to the virus ACE-2, a protein found in human cells. Plays a central role in the connection. Further research has shown that due to the five mutations in the spike protein found in SARS-Cov-2, it binds more strongly to ACE-2 in human cells than in SARS-Cov-1, which Has increased its ability to cause disease.

However, computer-assisted research has shown that some of the mutations in the six key molecules of the virus's spike protein are possible, which could be compared to the virus in human cells from ACE-2 to SARS-Cov-2. I can connect more firmly. Therefore, if the virus had been deliberately created in a laboratory, the changes in the spike protein of the virus would have been detected by computers, not the changes that actually existed in it.
In addition, at the end of November, an animal, Pengolin, was illegally taken to a market in Wuhan, China, in which the genetic material of the virus was found to be no more similar to that of human SARS-Cov-2. However, its spike protein The six key molecules found in N are very similar to human SARS-Cov-2, indicating that the bat virus found in China was the first to possibly be transmitted to Pengolin. The two viruses reproduced simultaneously in Pengolin's body, resulting in a virus whose genetic material was very similar to that of a bat but whose spike protein was similar to that of the Pengolin virus. The virus was transmitted from pengolin to humans.SARS-CoV-2 origin, assumptions and reality,Sars Vs Covid 19, facts about sars,info about sars, composition and structure of sars, transmission of sars.
