Evidence of constant diversification punctuated by a mass extinction in the African cycads [PDF]

open access: yes
The recent evidence that extant cycads are not living fossils triggered a renewed search for a better understanding of their evolutionary history. In this study, we investigated the evolutionary diversification history of the genus Encephalartos, a ...
