Coauthor of a Science study on SARS-CoV-2 molecular epidemiology and zoonotic origins
If lineages A and B arose from separate introductions, then the MRCA of SARS-CoV-2 was not in humans, and it is the tMRCAs of lineages A and B that are germane to the origins of SARS-CoV-2.Disputed (Aug 26, 2022)

Primary source is the multi-author Science paper by Pekar et al.; this is paper text, not a statement attributable to Edyth Parker alone. Multi-author journal-article text is not a verifiable single-author quote.

The exact sentence beginning "If lineages A and B arose from separate introductions" appears in the cited article, and the PMC URL is indexed with that same sentence; the paper is dated 2022-08-26. However, the source is a standard multi-author Science paper—Pekar, Magee, Parker, and many others—not a statement attributed to Edyth Parker alone. The submitted text is also a truncated excerpt, with the article continuing after it with a parenthetical about "the timing of their shared ancestor." Under this schema, that makes the single-author attribution disputed. ([pure.ed.ac.uk](https://www.pure.ed.ac.uk/ws/portalfiles/portal/301153226/science.abp8337.pdf))
