Could you link to an article or journal that strongly suggests it's natural over artificial based on the sequencing, please.
What is truly bizarre is that the gene sequence of this common ancestor RaTG13 was only released in late January 2020 by Shi's lab in Wuhan – the same lab in question regarding the leak.
For the moment, I am hesitant to trust any research premised on analysis of RaTG13.
I think accidental release of a naturally evolved virus is still a plausible hypothesis. To discount it as "conspiracy theory" seems to be wishful thinking.
I will continue to monitor findings on this until more conclusive, non-RaTG13 derived evidence is available.
