Virus-Infected Neanderthals Might Become Homo Sapiens
There is a theory that Neanderthals evolved into the modern mankind through contamination of viruses that changed their DNA.
Viruses can bring some genes into human cells and embed them into our DNA. There is also a theory than evolution of the mankind was accelerated by this function of viruses that contaminated human cells. And other animals must have also evolved through contamination with viruses that changed their DNAs.
So, it is no wonder that every one of the modern mankind possesses genes that were originated in Neanderthals, since our ancestors might include Neanderthals who had been contaminated by viruses and undergone DNA change to become Homo sapiens or anatomically modern humans. Put simply, not all the Neanderthals went extinct, but some Neanderthals survived as Homo sapiens through change in DNA by contamination with some viruses.
These traits that can be traced back to the era of co-existence of Neanderthals and Homo sapiens must be related to receptivity to viruses. Therefor, some races of today may be prone to be more easily contaminated by some viruses, such as corona-viruses, depending on the degree to proximity of DNA to Neanderthals.
According to another study, in some areas of the human genome the genes that can react mutually with viruses are condensed. And in these genes that can react mutually with viruses are condensed, molecules that directly react with RNA viruses such as HIV and influenza viruses are condensed.
Anyway, viruses can enter into our cells, change part of our genes on DNA, and accelerate evolution of the mankind. It also means that we cannot be completely free from viruses as long as our bodies are built with cells that accept genes carried in by viruses.
So, the mankind will develop science to control viruses in our bodies and cells or our DNA where viruses can embed new genes. However, the technology developed for this purpose may be abused to alter the basic physical structure of a man, which may lead to more danger for existence of the mankind.
Therefore, it is natural that the end of the world will come with influence or aftermath of contamination or pandemics by some fatal viruses.

John 8 King James Version
22 Then said the Jews, Will he kill himself? because he saith, Whither I go, ye cannot come.
23 And he said unto them, Ye are from beneath; I am from above: ye are of this world; I am not of this world.
24 I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins.
25 Then said they unto him, Who art thou? And Jesus saith unto them, Even the same that I said unto you from the beginning.
26 I have many things to say and to judge of you: but he that sent me is true; and I speak to the world those things which I have heard of him.
