Title

Gregory L Owens; Kaichi Huang; Marco Todesco; et al. Molecular Biology and Evolution 2023. doi:10.1093/molbev/msad013
Other claims from this paper (6)
- Association Support for the major species tree falls as recombination rate rises.
- Observation Hybridization is associated with origins of three putative Helianthus hybrid species.
- Observation The inferred hybridization events are older than previously suggested.
- Observation H. anomalus and H. deserticola appear to derive from one hybridization event involving an unexpected donor.
- Observation The findings are consistent with two ancient independent homoploid hybrid speciation events, without proving them.
- Observation Signals of introgression extend across and beyond Helianthus.
