Dynamics of Adaptive Radiation
Biologists have long been fascinated by the exceptionally high diversity displayed by some evolutionary groups (e.g.,Darwin’s finches, Anolis lizards, cichlid fishes of the African Great Lakes). Adaptive radiation in such clades is not onlyspectacular, but is also an extremely complex process influenced by a variety of ecological, genetic, and developmentalfactors and strongly depen...

متن کاملWhat we have also learned: adaptive speciation is theoretically plausible.
A recent Perspectives article by Gavrilets (2003) on the theory of speciation ignored advances in understanding processes of adaptive speciation, in which the splitting of lineages is an adaptation caused by frequency-dependent selection. Adaptive, or sympatric, speciation has been modeled since the 1960s, but the large amount of attention from both empirical and theoretical biologists that ada...
متن کاملCOMMENTARY The way the world might be
Theoreticians are interested in the way the world might be, seeking theories of ‘elegant and economical...mathematical form, in the expectation that they will prove the ones realized in nature’ (Polkinghorne, 1983, p. 9–10). Empiricists, on the contrary, prefer to know ‘The Way the World Is’ (as in Polkinghorne’s title). Ideally, our understanding advances by an interplay between the two. As Da...
متن کاملDynamic patterns of adaptive radiation.
Adaptive radiation is defined as the evolution of ecological and phenotypic diversity within a rapidly multiplying lineage. When it occurs, adaptive radiation typically follows the colonization of a new environment or the establishment of a "key innovation," which opens new ecological niches and/or new paths for evolution. Here, we take advantage of recent developments in speciation theory and ...
