Interesting quote from the abstract:
> ...the natural origin theory remains supported by several novel coronaviruses published after the start of the outbreak....Here, however, we use in-depth analyses of the available data and literature to prove that these novel animal coronaviruses do not exist in nature and their sequences have been fabricated. In addition, we also offer our insights on the hypothesis that SARS-CoV-2 may have originated naturally from a coronavirus that infected the Mojiang miners.
