author keywords: deep genome skimming; genomic discordance; historical biogeography; massive extinction; reticulate evolution; single-copy nuclear genes

MeSH headings : Fossils; Hybridization, Genetic; Malus / genetics; Phylogeny; Plastids

TL;DR: The conflict analysis demonstrated that ILS, hybridization, and allopolyploidy could explain the widespread nuclear gene tree discordance and a historical biogeographic analysis integrating living and fossil data supported a widespread East Asian-western North American origin of Malus s.l.
