Audits the raw sequencing/assembly records behind RaTG13, MP789 (pangolin) and RmYN02 — the genomes cited to argue SARS-CoV-2’s novel features are natural — and reports discrepancies: RmYN02’s claimed S1/S2 “insertion” may actually be a 6-nucleotide deletion relative to SARS-CoV-2 rather than a matching insertion, and the RaTG13/RmYN02 raw metagenomic datasets contain reads the authors interpret as possible contamination. Calls for independent re-assembly of the underlying sequencing data. relevance_note: a direct challenge to the evidentiary quality of the “natural precedent” comparator genomes (RaTG13, RmYN02) that zoonosis-side genome-structure arguments lean on.
