Abstract

Major phenotypic changes evolve in parallel in nature by molecular mechanisms that are largely unknown. Here, we use positional cloning methods to identify the major chromosome locus controlling armor plate patterning in wild threespine sticklebacks. Mapping, sequencing, and transgenic studies show that the Ectodysplasin (EDA) signaling pathway plays a key role in evolutionary change in natural populations and that parallel evolution of stickleback low-plated phenotypes at most freshwater locations around the world has occurred by repeated selection of Eda alleles derived from an ancestral low-plated haplotype that first appeared more than two million years ago. Members of this clade of low-plated alleles are present at low frequencies in marine fish, which suggests that standing genetic variation can provide a molecular basis for rapid, parallel evolution of dramatic phenotypic change in nature.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The lack of a coding change at the eda locus in sticklebacks associated with the loss of dermal plates has led to the argument that evolution of this trait is due to changes at cis-regulatory elements controlling eda expression.

    “The lack of a coding change at the eda locus in sticklebacks that is associated with the loss of dermal plates has lead to the argument that, in this case, evolution of this trait is due to changes at cis-regulatory elements controlling eda expression [33].”
  • Evidence from the stickleback suggests that genetic variance at the eda locus underlies differences in the extent of dermal plate formation in diverged populations.

    “Additionally, evidence from the stickleback, Gasterosteus aculeatus, suggests that genetic variance at the eda locus underlies differences in the extent of dermal plate formation in diverged populations of this species [33].”

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.
