SARS-CoV-2 has genetic features indicating natural zoonotic evolution rather than human engineering
the verdict
SUPPORTED
the evidence backs this
confidence 76/100
Multiple genomic and phylogenetic studies indicate that SARS-CoV-2 possesses genetic features consistent with natural zoonotic evolution and spillover from wildlife rather than human engineering.
