Scientists from Oxford University (UK) discovered that the most recent general ancestor of SARS-COV-1 and SARS-COV-2 viruses, the current Covid-19 disease caused, existed 21 thousand years ago, 'old' more than 30 times more than before. This new discovery is published in the magazine Current Biology.0: 00/1: 30nam Southern Scientists British has identified the oldest Corona virus. (Artwork, Source: Wikimedia) According to scientists, viruses are capable of developing rapidly in a short period of time, but at the same time they still have to adapt to the host, making it considerable limitations With freedom to accumulate mutations without reducing their structance. That leads to clear slowing in the evolutionary rate of viruses over time
. The new study came to the speed decline of the recorded virus through observation, facilitating scientists to monitor the evolution of the virus to the form of their "aquatic group". Although the models Existing evolution usually does not allow the determination of the difference of viruses for a period of several hundred to several thousand years, but a new evolutionary model helps us evaluate a trusted way The appearance of new viruses on the time scale, equivalent to the evolutionary development of animals and plants on the Earth. Currently, scientists can not only rebuild evolutionary history Viruses related to SARS-COV-2, but also with many types of RNA and DNA of viruses in the past past
For example, the predictions of viruses that cause hepatitis C are coincided with the idea that it has spreads in human populations for nearly half a million years. Thus, the hepatitis C virus may have spread through the world due to human migration process from Africa to other regions of about 150 thousand years ago. (According to Current Biology) . Dịch vụ:
