"An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG III". Flowering plant. The ancestors of flowering plants diverged from gymnosperms around 245–202 million years ago, and the first flowering plants known to exist are from 160 million years ago.
They diversified enormously during the Lower Cretaceous and became widespread around 120 million years ago, but replaced conifers as the dominant trees only around 60–100 million years ago. Angiosperm derived characteristics[edit] Flowers The flowers, which are the reproductive organs of flowering plants, are the most remarkable feature distinguishing them from the other seed plants. Flowers aid angiosperms by enabling a wider range of adaptability and broadening the ecological niches open to them.
These distinguishing characteristics taken together have made the angiosperms the most diverse and numerous land plants and the most commercially important group to humans. Evolution[edit] In 2013 flowers encased in amber were found and dated 100 million years before present. Classification[edit] Angiosperm Phylogeny Website. Angiosperms.
