The Wall Street Journal May 30-31 Saturday-Sunday edition has an article “So Where Did the Virus Come From” by Matt Ridley on page C3 That is the most comprehensive I have yet read.
Sample quote:
... but a new paper by two scientists from the Agharkar Research Institute in Prune, India, show that it is the same as a published sample with a different name that was collected from an abandoned mineshaft in southern Yunnan in 2013, following an outbreak of pneumonia-like illness that killed three miners there the year before.
End quote
There is much more in the article, including a section about labs both in Chapel Hill NC and Wuhan, China, that intentionally cut and spliced genes into Coronaviruses to see if the modified viruses became more infectious or deadly.
