Factors promoting polyploid persistence and diversification and limiting diploid speciation during the K-Pg interlude.

Current opinion in plant biology - 1 Apr 2018

Levin Donald A, Soltis Douglas E

Abstract excerpt

The large wave of polyploidization following the Cretaceous-Paleogene (K-Pg) mass extinction has been explained by enhanced polyploid persistence arising from adaptive properties of the polyploids themselves, as well as an increase in unreduced gamete production and diploid hybridization. We propose that the demise of diploids afforded opportunities for polyploid establishment and expansion into novel habitats....
