ABSTRACTThe origins of interactions between angiosperms and fruit‐eating seed dispersers have attracted much attention following a seminal paper on this topic byTiffney (1984). This review synthesizes evidence pertaining to key events during the evolution of angiosperm–frugivore interactions and suggests some implications of this evidence for interpretations of angiosperm–frugivore coevolution. The most important conclusions are: (i) the diversification of angiosperm seed size and fleshy fruits commenced around 80 million years ago (Mya). The diversity of seed sizes, fruit sizes and fruit types peaked in theEocene around 55 to 50 Mya. During this first phase of the interaction, angiosperms and animals evolving frugivory expanded into niche space not previously utilized by these groups, as frugivores and previously not existing fruit traits appeared. From theEocene until the present, angiosperm–frugivore interactions have occurred within a broad frame of existing niche space, as defined by fruit traits and frugivory, motivating a separation of the angiosperm–frugivore interactions into two phases, before and after the peak in the earlyEocene. (ii) The extinct multituberculates were probably the most important frugivores during the early radiation phase of angiosperm seeds and fleshy fruits. Primates and rodents are likely to have been important in the latter part of this first phase. (iii) Flying frugivores, birds and bats, evolved during the second phase, mainly during theOligocene andMiocene, thus exploiting an existing diversity of fleshy fruits. (iv) A drastic climate shift around theEocene–Oligocene boundary (around 34 Mya) resulted in more semi‐open woodland vegetation, creating patchily occurring food resources for frugivores. This promoted evolution of a ‘flying frugivore niche’ exploited by birds and bats. In particular, passerines became a dominant frugivore group worldwide. (v) Fleshy fruits evolved at numerous occasions in many angiosperm families, and many of the originations of fleshy fruits occurred well after the peak in the earlyEocene. (vi) During periods associated with environmental change altering coevolutionary networks and opening of niche space, reciprocal coevolution may result in strong directional selection formative for both fruit and frugivore evolution. Further evidence is needed to test this hypothesis. Based on the abundance of plant lineages with various forms of fleshy fruits, and the diversity of frugivores, it is suggested that periods of rapid coevolution in angiosperms and frugivores occurred numerous times during the 80 million years of angiosperm–frugivore evolution.
