The geography of speciation has long been contentious. In recent years, phylogenetic
approaches have been proposed to determine the geographical mode of speciation. If …

Cichlid fishes constitute one of the most species-rich families of vertebrates. In addition to
complex social behaviour and morphological versatility, they are characterised by extensive …

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 …

Rapid evolutionary radiations provide insight into the fundamental processes involved in
species formation. Here we examine the diversification of one such group, the cichlid fishes …

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

Abstract With more than 3,000 species, the fish family Cichlidae is one of the most species-
rich families of vertebrates. Cichlids occur in southern and central America, Africa …

Repeated evolution of the same phenotypic difference during independent episodes of
speciation is strong evidence for selection during speciation. More than 1,000 species of …

Water level fluctuations are important modulators of speciation processes in tropical lakes, in
that they temporarily form or break down barriers to gene flow among adjacent populations …

The idengification of incipient ecological species represents an opportunity to investigate
current evolutionary process where adaptive divergence and reproductive isolation are …
