O-33 - Positive market environmental samples concentrated at a single live-mammal vendor stall
Worobey et al. re-mapped the China CDC environmental positives onto stall locations and found the earliest viral contamination physically co-located with a live-mammal-selling stall in the SW corner of the market.

Why this is evidence
Earliest contamination localizing to a live-mammal vendor stall is predicted by H-14 (wildlife spillover); a human/cold-chain seed (H-15) would not concentrate at the live-mammal stall.
