Do you wonder if #SARSCoV2 came from an animal or a lab?
I finally had the time to read this paper. I shall discuss in this thread observations relevant for virus emergence and why this work further discredits the lab origin theory. #COVID

1. Bats were collected from an irrigation pipe in Thailand. So, if you think that bats with SARS-related #coronaviruses only exist in remote caves, then you are wrong. Like most wildlife, bats can also cover long distances.
2. Coronavirus detected in Rhinolophus acuminatus in this study are evolutionary closely related to #SARSCoV2 and other SARS2-related coronaviruses detected in bats.
3. The lab escape theory used the detection of a furin cleavage site in #SARSCoV2 as a 'man-made' artifact. This has already been discredited by other studies. In this study, bat #coronaviruses shared part of the furin cleavage site. No man-made manipulations required.
4. Rhinolophus bats (which are widespread in South Asia) are natural reservoirs of SARS2-related coronaviruses. Study also identified that pangolins have cross-reacting antibodies. Not certain if pangolins are intermediate hosts or just accidentally infected (like humans).
END.
