Angiosperm. The evolution of plants has resulted in a wide range of complexity, from the earliest algal mats, through multicellular marine and freshwater green algae, terrestrial bryophytes, lycopods and ferns, to the complex gymnosperms and angiosperms (flowering plants) of today. The angiosperm radiation hypothesis proposes that: Certain primate traits were responses to the evolutionary spread of fruit tress during the Cenozoic. The increased biosynthetic capacity of angiosperms in producing secondary metabolites, providing attractants, repellents, and other kinds of allelochemicals, has to be viewed in connection with their coevolution with arthropods, fungi, vertebrates, and other groups of organisms (Kubitzki and Gottlieb 1984a,b).
