I wasn't going to waste my time after you said it's very peculiar for a nature made virus to mutate. That's so far from being true that I know the video is a waste of my time. From Healthline:
“In the world of RNA viruses, change is the norm. We expect RNA viruses to change frequently. That’s just their nature,” said Dr. Mark Schleiss, a pediatric infectious disease specialist and investigator with the Institute for Molecular Virology at the University of Minnesota.
SARS-CoV-2 is no exception, and over the past few months it has been mutating.
But the virus has mutated at a very slow pace. And when it does mutate, the new copies aren’t far off from the original virus.
