The Genetics of Adaptation: A Reassessment
Abstract
We review both the theory and the data supporting the neo-Darwinian claim that adaptation results from the accumulation of many alleles of small effect. The theory supporting this "micromutationist" view is inconclusive. Furthermore, the evidence from genetic analysis is mixed: although some adaptations are apparently based on many genes of small effect, others clearly involve major genes. Most genetic analyses, moreover, have lacked the power to detect major genes. We conclude that, although the neo-Darwinian view of adaptation may be correct, it is not strongly supported by evidence. The introduction of molecular approaches may, however, finally allow us to resolve this question.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
