Species diversity varies greatly across the different taxonomic groups that comprise the Tree
of Life (ToL). This imbalance is particularly conspicuous within angiosperms, but is largely
unexplained. Seed mass is one trait that may help clarify why some lineages diversify more
than others because it confers adaptation to different environments, which can subsequently
influence speciation and extinction. The rate at which seed mass changes across the
angiosperm phylogeny may also be linked to diversification by increasing reproductive …
