In February 2020, there were only 2 things you could believe..
1) That it escaped from the handy dandy nearby bio lab or
2) Some guy bought the lucky bat from a barrel of water and ate it..
Gee, I wonder which one it was?????
“origin nor do they add any new information in support of lab origin.”
folks, here is the evidence of lab origin the media is too stupid to talk about.

Artificial coronaviruses have been made and published about 6 times prior to Covid emerging. The process used is Golden Gate Cloning. Natural coronaviruses are all about 30k nucleotides (nt). Viruses are cloned by using the cell mechanism in E. Coli bacteria to copy the virus. That’ how viruses survive, they get into cells and replicate themselves using the equipment in the host cell. But DNA fragments longer than 7k nt cannot be easily inserted into E. Coli. So to clone a 30k virus you have to chop it up into 5 or more pieces. If you make more pieces than that, it is difficult to put all the pieces back together. To split the virus requires the use of “restriction enzymes” which recognize a pattern of nt in the virus and split the virus ONLY WHERE THAT PATTERN APPEARS. In natural coronoviruses that restriction enzyme recognition sequence appears at random places. In Covid19 the sequences appear conveniently at regular intervals, as they do in all artificilly created virures. The chance of Covid occurring naturally is less than 1%, arguably 1 in a million. Read the paper. Google “type IIs restriction enzyme” “Golden Gate cloning”, go to the website of New England biosciences..
