trailReported intermediate A-B SARS-CoV-2 genomes are genuine biological intermediates, not sequencing artifacts
The correct rooting of the early SARS-CoV-2 phylogenetic tree is uncertain
Intermediate A-B SARS-CoV-2 genomes existed among early human cases
Excluding intermediate lineage A/B SARS-CoV-2 genomes materially affects Pekar et al.'s inferred number of spillovers
