HOW COMMON IS HOMOPLOID HYBRID SPECIATION?: PERSPECTIVE
Abstract
Hybridization has long been considered a process that prevents divergence between species. In contrast to this historical view, an increasing number of empirical studies claim to show evidence for hybrid speciation without a ploidy change. However, the importance of hybridization as a route to speciation is poorly understood, and many claims have been made with insufficient evidence that hybridization played a role in the speciation process. We propose criteria to determine the strength of evidence for homoploid hybrid speciation. Based on an evaluation of the literature using this framework, we conclude that although hybridization appears to be common, evidence for an important role of hybridization in homoploid speciation is more circumscribed.

Homoploid hybrid speciation is thought to be rare because of the challenge of evolving RI from parental populations.
“In contrast to polyploid hybrid speciation, which is the focus of the next section of this review, homoploid hybrid speciation is thought to be rare because of the challenge of evolving RI from parental populations (Rieseberg, 1997; Buerkle et al., 2000; Schumer et al., 2014; but see Nieto Feliner et al., 2017).”

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.
