Thanks that is an interesting paper. It certainly calls into question when covid first arose and the Wuhan origins.
It appears well done by some reputable scientists. A reputable peer reviewed journal.
More study is still needed, I suspect it will take years to figure out where and how the covid virus came about, and all questions may never be answered.
Where abouts in North Vancouver are you? I went fishing out of Port Hardy in July, is that close? My first trip, it's a very impressive place!
