Evolutionary Links Between Angiosperms and Animals • Pollination of flowers and transport of seeds by animals are two important relationships in terrestrial ecosystems • Clades with bilaterally symmetrical flowers have more species than those with radially symmetrical flowers • This is likely because bilateral symmetry affects the movement of pollinators and reduces gene flow in diverging populations Video: Bee Pollinating Video: Bat Pollinating Agave Plant Copyright © 2008 Pearson Education, Inc., publishing as Pearson Benjamin Cummings
