Oh, here’s a key statement, ‘deliberate laboratory recombination of an as-yet-undisclosed natural ancestor of SARS-CoV-2., that comes
from this more full quote in the article” “The question of binding sites is important to the debate about the origins of SARS-CoV-2. Distinctive binding sites on SARS-CoV-2’s spike protein confer “near-optimal” binding and entry of the virus into human cells, and make SARS-CoV-2 more contagious than SARS-CoV. Scientists have argued that SARS-CoV-2’s unique binding sites could have originated either as a result of natural spillover in the wild or deliberate laboratory recombination of an as-yet-undisclosed natural ancestor of SARS-CoV-2.”
