Researchers have found evidence that a coronavirus epidemic swept East Asia some 20,000 years ago and was devastating enough to leave an evolutionary imprint on the DNA of people alive today.
The new study suggests that an ancient coronavirus plagued the region for many years, researchers say. The finding could have dire implications for the Covid-19 pandemic if it’s not brought under control soon through vaccination.
Four other coronaviruses can also infect people, but they usually cause only mild colds. Scientists did not directly observe these coronaviruses becoming human pathogens, so they have relied on indirect clues to estimate when the jumps happened.
Coronaviruses gain new mutations at a roughly regular rate, and so comparing their genetic variation makes it possible to determine when they diverged from a common ancestor.
The most recent of these mild coronaviruses, called HCoV-HKU1, crossed the species barrier in the 1950s. The oldest, called HCoV-NL63, may date back as far as 820 years.
“It should make us worry,” said David Enard, an evolutionary biologist at the University of Arizona who led the study, which was published on Thursday in the journal Current Biology. “What is going on right now might be going on for generations and generations.”
Until now, researchers could not look back very far into the history of this family of pathogens.
Over the past 20 years, three coronaviruses have adapted to infect humans and cause severe respiratory disease: Covid-19, SARS and MERS.
Studies on each of these coronaviruses indicate that they jumped into our species from bats or other mammals.

That is until sometime in the 1950s when one mild one mutated making 5.
Suddenly in the last 20 years after we started doing gain of function research on corona viri 3 more have naturally mutated and are not mild.
Must be global warming.
That would explain why we’re extinct.
Lol I did not foresee this particular argument

But of course, the ancient history angle.
Bull Excrement!
Common cold.
“coronavirus plagued the region for many years”
*****
Never back to normal.
Hey look, it’s Covid18,000BC 🙄
Both the cold and flu bugs are corona virises.
No big deal. They locked down for 1,040,000 weeks and managed to eventually flatten the curve.
This may be the singularly most ridiculous piece of bulls$!t propaganda I’ve ever read.
This is the Ministry of Propaganda’s way of saying, “See, this is not the fault of our Chinese friends”.
I think they would have beat Fauci with a thigh bone and continued living normal lives.
NYT’s stories are getting worse than CNNs
Was there a stone-age Fauci grunting for everyone to wear rocks as masks?
/S !!!
One doesn’t have to read the entire article to know it’s gaslighting. One only has to see it was published by the New York Times.
20,000 years ago ape men learn to genetically modify Corona viruses from the alien monolith.
Feckit, we’re all going to die anyway.
It was probably Caveman Xi’s fault, but Dr Fau-cave didn’t help matters. Neither did all those mass hunting parties.
