Key innovations and the ecology of macroevolution

Hunter, John P·1998·Trends in Ecology & Evolution

Abstract

The origin or evolutionary `success' of taxa is often attributed to key innovations-aspects of organismal phenotype that promote diversification. Different ways of delimiting taxa and measuring `success' (i.e. number or longevity of species, morphological variety or differential control of energy) give rise to different ideas of how key innovations might operate. Key innovations may enhance competitive ability, relax adaptive trade-offs or permit exploitation of a new productive resource base. Recent key innovation studies comparing species richness in extant sister clades may miss important observations possible only with consideration of the fossil record, traditional higher taxa and phenotypic diversity.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • Key innovations have commonly been identified by diversification of the clade possessing the innovation, but such claims have proved difficult if not impossible to test.

    “Key innovations have commonly been identified by diversification of the clade possessing the innovation [8–10], but despite the continuing enthusiasm for key innovations, such claims have proved difficult if not impossible to test [11,12].”

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.
