This article from WLC might be helpful to some of the Catholics here that hold to an ancient Adam and Eve. Craig’s position is essentially a variant of many Catholics’ position
Does population genetics challenge a single-couple origin to humanity? In early 2017, Dr. Richard Buggs raised scientific concerns about Dennis Venema’s book, Adam and the Genome . His concerns were distinct and addition to concerns that Dr. Swamidass raised that year too. In late 2017, Dr. Venema responded at BioLogos, and a conversation grew. Together, several scientists did indeed find several fundamental mistakes with Dr. Venema’s argument against a single couple origin of humanity. Eventually, in 2020, even BioLogos began backing away from Venema’s scientific claims. In this article, Craig summarizes for a lay audience the science behind this shift. For technical readers, the forum thread for this article expounds and clarifies his summary with greater precision.
As a scientist, I am happy to answer any questions that arise about this.
