| Outline of Final Research Achievements |
Flowering plants (angiosperm) represent a major component of biodiversity on earth. Diversity of angiosperm has often been explained as the results of adaptation to a variety of growth environments or to a variety of pollinators (e.g., bee, butterfly, moth, and hummingbird). This prompted an expectation: synergistic action of natural selection from the growth environment and from pollinators may facilitate the diversification (speciation) of angiosperm. We examined this expectation and found that an important condition for this expectation is that plants that are better adapted to local growth conditions can attract pollinators better. This finding may be an important key for understanding the mechanisms that generate angiosperm diversity.
