This chapter discusses the evolutionary histories and geographic distributions of tropical plants and their vertebrate mutualists. It addresses the following questions: how widespread are vertebrate pollination and seed dispersal mutualisms in the phylogenies of angiosperms, birds, and mammals? How many times have these mutualisms evolved independently in these groups? To what extent is the evolution of pollination and seed dispersal mutualisms congruent or noncongruent in these phylogenies? Where have these mutualisms evolved? Are there evolutionary “hotspots” for these mutualisms and are these hotspots congruent for both mutualisms? And what are the temporal patterns of the evolution of these mutualisms and are these patterns congruent for both mutualisms? How long have specific groups of plants and their vertebrate mutualists been interacting?

Keywords:   evolutionary history, geographic distribution, tropical plants, mutualists, vertebrate pollination, seed dispersal mutualisms
