WebAngiosperms (flowering plants) are the most recent lineage of land plants to evolve. Fossil evidence indicates that flowering plants first appeared in the Lower Cretaceous , about 125 million years ago, and were rapidly diversifying by the Middle Cretaceous, about 100 million years ago. WebIt was probably very early in the evolutionary history of flowering plants that self-incompatibility was evolved, a mechanism that prevents flowers or plants from self-pollinating.
