Why this is evidence
The reservoir taxon is absent from Wuhan’s markets, so H-1 must route the virus into Huanan through an unobserved intermediate-host chain from ~1500 km away, whereas H-5 and H-6 (WIV bat-sampling programme, or a distant spillover with travel-borne introduction) supply that transport step directly. Mildly favours H-5/H-6 over H-1.
