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 …

The origins and development of the study of speciation, hybrid zones and phylogeography
are outlined using evolutionary iconography. This traces the ideas in this field from Lamarck …

A fully updated guide to the increasingly prevalent use of molecular data in ecological
studies Molecular ecology is concerned with how molecular biology and population genetics …

Sympatric speciation, the formation of species in the absence of geographical barriers,
remains one of the most contentious concepts in evolutionary biology. Although speciation …

Sex determination mechanisms differ among animal species, but it is not clear how these
differences evolve. New sex determiners may arise in response to sexual conflicts, which …

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 …

▪ Abstract Cichlid fishes (Perciformes: Teleostei) found in the lakes of Africa have served as
model systems for the study of evolution. The enormous number of species (1000 in Lake …

Both ornaments and weapons of sexual selection frequently exhibit prolific interspecific
diversity of form. Yet, most studies of this diversity have focused on ornaments involved with …

A gene tree is an evolutionary reconstruction of the genealogical history of the genetic
variation found in a sample of homologous genes or DNA regions that have experienced …

The question of how genetic variation translates into organismal diversity has puzzled
biologists for decades. Despite recent advances in evolutionary and developmental …
