Id Subject Object Predicate Lexical cue
T36 0-287 Sentence denotes Evolution is stepwise and accrues mutations gradually over time, whereas synthetic constructs would typically use a known backbone and introduce logical or targeted changes instead of the randomly occurring mutations that are present in naturally isolated viruses such as bat CoV RaTG13.
T37 288-422 Sentence denotes In our view, there is currently no credible evidence to support the claim that SARS-CoV-2 originated from a laboratory-engineered CoV.
T38 423-571 Sentence denotes It is more likely that SARS-CoV-2 is a recombinant CoV generated in nature between a bat CoV and another coronavirus in an intermediate animal host.
T39 572-669 Sentence denotes More studies are needed to explore this possibility and resolve the natural origin of SARS-CoV-2.
T40 670-917 Sentence denotes We should emphasize that, although SARS-CoV-2 shows no evidence of laboratory origin, viruses with such great public health threats must be handled properly in the laboratory and also properly regulated by the scientific community and governments.
