> ...what is the supporting evidence for the alternate "zoonotic transmission" theory? This is a reasonable question and should be answered rather than downvoted. A study released a few months ago (https://news.ycombinator.com/item?id=30487145 https://news.ycombinator.com/item?id=30487145) found that two strains of SARS-CoV-2 emerged at the Wuhan market in November-December 2019, Lineage A and Lineage B. From the submitted article, "it’s extremely improbable that two distinct lineages of SARS-CoV-2 could have been derived from a laboratory and then coincidentally ended up at the market."
