Seed size and its rate of evolution correlate with species diversification across angiosperms
Angiosperms are one of the most species-rich clades on Earth and have dominated terrestrial plant communities since the Late Cretaceous Period. The astounding diversity of flowering plants is distributed extremely unevenly across the Tree of Life (ToL). Each of the 5 most species-rich angiosperm families contains more than 10,000 species, while more than 200 families contain less than 100 species each.
