Do you have evidence for this claim. I’ve posted evidence to the contrary but perhaps you are better informed.
Evidence of it's mutation?
I found this while googling coronavirus:
"Evolution
The most recent common ancestor (MRCA) of all coronaviruses has been placed at around 8000 BCE.[26] The MRCAs of the Alphacoronavirus line has been placed at about 2400 BCE, the Betacoronavirus line at 3300 BCE, the Gammacoronavirus line at 2800 BCE, and the Deltacoronavirus line at about 3000 BCE. It appears that bats and birds, as warm-blooded flying vertebrates, are ideal hosts for the coronavirus gene source (with bats for Alphacoronavirus and Betacoronavirus, and birds for Gammacoronavirus and Deltacoronavirus) to fuel coronavirus evolution and dissemination.[27]
Bovine coronavirus and canine respiratory coronaviruses diverged from a common ancestor in 1951.[28] Bovine coronavirus and human coronavirus OC43 diverged around the 1890s. Bovine coronavirus diverged from the equine coronavirus species at the end of the 18th century.[29]
The MRCA of human coronavirus OC43 has been dated to the 1950s.[30]
MERS-CoV, although related to several bat coronavirus species, appears to have diverged from these several centuries ago.[31] The human coronavirus NL63 and a bat coronavirus shared an MRCA 563–822 years ago.[32]
The most closely related bat coronavirus and SARS-CoV diverged in 1986.[33] A path of evolution of the SARS virus and keen relationship with bats have been proposed. The authors suggest that the coronaviruses have been coevolved with bats for a long time and the ancestors of SARS-CoV first infected the species of the genus Hipposideridae, subsequently spread to species of the Rhinolophidae and then to civets, and finally to humans.[34][35]
Alpaca coronavirus and human coronavirus 229E diverged before 1960"
