The cost of DNA sequencing continues to fall, which makes it feasible to develop genomic
resources for new model species that are well suited for studying questions in evolutionary …

▪ Abstract To assess the frequency and importance of reinforcement in nature we must begin
by looking for its signature in the most likely places. Theoretical studies can pinpoint …

Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can
cause a single ancestral species to differentiate into an impressively vast array of species …

The study of speciation has become one of the most active areas of evolutionary biology,
and substantial progress has been made in documenting and understanding phenomena …

Sexual selection has a reputation as a major cause of speciation, one of the most potent
forces driving reproductive isolation. This reputation arises from observations that species …

Some of the most spectacular and diverse traits in animals are the signals used to attract
mates. Closely related species often differ dramatically in signaling traits, in spite of similarity …

A large number of mathematical models have been developed that show how natural and
sexual selection can cause prezygotic isolation to evolve. This article attempts to unify this …

Cichlid fishes are amazing creatures. In terms of sheer number of species, they are the most
successful of all families of vertebrate animals, and the extent and speed with which they …

Sympatric speciation, the origin of two or more species from a single local population, has
almost certainly been involved in formation of several species flocks,,,, and may be fairly …

The endemic cichlid fishes of Lakes Malawi, Tanganyika and Victoria are textbook examples
of explosive speciation and adaptive radiation, and their study promises to yield important …
