Regulatory evolution and the origin of the bilaterians

Abstract

The adult body plan of bilaterians is achieved by imposing regional specifications on pluripotential cells. The establishment of spatial domains is governed in part by regulating expression of transcription factors. The key to understanding bilaterian evolution is contingent on our understanding of how the regulation of these transcription factors influenced bilaterian stem-group evolution.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

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 bilaterian-cnidarian ancestor likely lived well before the Cambrian.

    “Molecular and morphological phylogenies agree that the bilaterian stem group emerged from a common ancestor of bilaterians and cnidarians, which probably existed much deeper in time (Peterson and Eernisse, 2001;Medina et al., 2001;Peterson and Davidson, 2000).”

  • Both molecular and morphological phylogenies indicate that the bilaterian stem lineage arose from an ancestor shared with cnidarians.

    “Molecular and morphological phylogenies agree that the bilaterian stem group emerged from a common ancestor of bilaterians and cnidarians, which probably existed much deeper in time (Peterson and Eernisse, 2001;Medina et al., 2001;Peterson and Davidson, 2000).”

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.
