THEY HAVE DEVELOPED A BENEFICIAL MUTATION
On the other hand, Souilmi said researchers have found that a group affected by the coronavirus in these populations has developed a beneficial mutation that helps protect themselves.
Stating that those who have the mutation have an “advantage” in terms of survival, Souilmi said, “In other words, the number of people with the mutation in the population over time exceeded the others. After a long period of exposure, it left a very clear mark in the genomes of their descendants. In this way, we were able to detect an epidemic that occurred 20,000 years ago.”
