Detailed understanding of how a n animal virus jumped species boundaries to infect humans so productively will h elp in the prevention of future zoonotic events. For example, if SARS-CoV-2 pre- adapted in another animal species, then there is the risk of future re-emergence events. In contrast, if the adaptive process occurred in humans, then even if repeated zoonotic transfers occur, they are unlikely to take off without the sam e series of mutations. In addition, identifying the closest viral relatives of S ARS-CoV-2 circulating in animals will greatly assist studies of viral function. Indeed, the availability of the RaTG13 bat sequence helped reveal key RBD mutati ons and the polybasic cleavage site. The genomic features described here may exp lain in part the infectiousness and transmissibility of SARS-CoV-2 in humans. Al though the evidence shows that SARS-CoV-2 is not a purposefully manipulated viru s, it is currently impossible to prove or disprove the other theories of its ori gin described here. However, since we observed all notable SARS-CoV-2 features, including the optimized RBD and polybasic cleavage site, in related coronaviruse s in nature, we do not believe that any type of laboratory-based scenario is pla usible. More scientific data could swing the balance of evidence to favor one hy pothesis over another. Obtaining related viral sequences from animal sources wou ld be the most definitive way of revealing viral origins. For example, a future observation of an intermediate or fully formed polybasic cleavage site in a SARS -CoV-2-like virus from animals would lend even further support to the natural-se lection hypotheses. It would also be helpful to obtain more genetic and function al data about SARS-CoV-2, including animal studies. The identification of a pote ntial intermediate host of SARS-CoV-2, as well as sequencing of the virus from v ery early cases, would similarly be highly informative. Irrespective of the exac t mechanisms by which SARS-CoV-2 originated via natural selection, the ongoing s urveillance of pneumonia in humans and other animals is clearly of utmost impor tance. ============================== 針對紅字重點(鄉民爭論部分)翻譯一下: 儘管證據證明SARS-CoV-2不是故意操縱的病毒,但此篇的內容目前是不可能去證明或反駁其 他理論描述的病毒起源。 但是,由於我們觀察了自然界中冠狀病毒SARS-CoV-2所有值得注 意的特徵,包括優化的RBD和多鹼基切割位點 (including the optimized RBD and polybas ic cleavage site這句因為我不是相關專業,所以是丟google的,但不影響爭論點),因此 我們認為此病毒是來自實驗室的理論是不合理的。 更多的科學數據可能會改變結果,使其 中一種理論更加有利。 ================================ 就結論看來,作者僅認為病毒不來自實驗室就這樣。 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 49.216.65.78 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/Gossiping/M.1585535295.A.3BD.html
