Scientists are still investigating the origin of the COVID-19 virus which has paralysed huge areas of the planet - but one theory suggests it isn’t as new as we think.
A study recently published in Nature highlighted the fact that the virus is definitely not man-made, and is the product of natural evolution.

But ScienceAlert reports it also suggests a scenario where the virus has been circulating undetected for some time, possibly years.
The researchers suggest that it’s possible the virus could have “jumped” into humans many times, writing: “Sufficient opportunity could have arisen if there had been many prior zoonotic events that produced short chains of human-to-human transmission over an extended period.”
