Evolutionary radiation of the Eurasian Pinus species under pervasive gene flow

open access: yesNew Phytologist, Volume 242, Issue 5, Page 2353-2368, June 2024.
Summary Evolutionary radiation, a pivotal aspect of macroevolution, offers valuable insights into evolutionary processes. The genus Pinus is the largest genus in conifers with c. 90% of the extant species emerged in the Miocene, which signifies a case of rapid diversification. Despite this remarkable history, our understanding of the mechanisms driving
