Yes, I read that you said that mutations cannot be seen in real time.
That's wrong. You don't understand biology.
SARS-CoV-2, a novel coronavirus mostly known as COVID-19 has created a global pandemic. The world is now immobilized by this infectious RNA virus. As of June 15, already more than 7.9 million people have been infected and 432k people died. This RNA virus has the ability to do the mutation in the...

Wrong.
It is the person who wrote the article you linked, who does not know what a mutation is.
Virus frequently change, but that is because they just dump their RNA into a cell nucleus and it can combine with other genetic material in that nucleus.
But that is NOT a mutation, but more of a hybrid.
A mutation is a totally random damage, like from radiation or something.
When a couple get married and have a kid, the kid is not identical to either parent, but it is NOT a mutation.
This person is using a definition of mutation for ANY change, and that is wrong.
These virus variants are NOT real time mutations, at all, in any way.
That is easy to prove in that they are appearing on all continents at about the same time.
If they were a mutation, they would have a singular source and easily traced.
So most likely these are ancient mutations being made more common by natural selection, meaning what works best in humans.
