The early cases cluster around the wet market. [...] So that and the verified presence of SARS-CoV-2 RNA samples in close proximity to animal DNA, is what we consider strong evidence. It's not proof. Proof is going to be extremely hard to obtain now, possibly never, for either hypothesis, but the balance of evidence impresses virologists, or most of us, in favor of the zoonotic wet market origin.

Statement relation comments

AI Verified Relevant: the quote directly addresses the statement’s core issue by treating the early-case cluster around the Huanan/wet market as part of the evidence for a market-origin emergence, not merely a testing artifact. In the source context, Moore pairs the clustering with market environmental samples near animal DNA and says this supports a zoonotic wet-market origin, making a clear stance on the complete statement substantially more likely.

Vote answer comments

AI Verified He says the early cases 'cluster around the wet market' and that, together with the RNA/animal-DNA findings, this is 'strong evidence' whose 'balance' favors a 'zoonotic wet market origin.' That strongly implies the clustering is evidence of where the virus emerged, not merely where investigators happened to look.
