O-21 - Pekar 2022 reported two-introduction Bayes factor fell from ~60 to ~4.3 after the 2024 coding-error erratum
Weissman re-reads Pekar et al. 2022 (P2022) as the data basis; these figures describe P2022’s own reported result (original ~60, post-erratum ~4.3), not a new dataset.

Why this is evidence
The Bayes factor is the headline quantitative measure of support for two introductions (H-5) over one (H-16); it still points toward H-5, but the erratum’s correction moved it sharply toward parity, weakening the case for separate introductions.
