Microsatellite markers are routinely used to investigate the genetic structuring of natural
populations. The knowledge of how genetic variation is partitioned among populations may …

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 …

Sympatric speciation has become increasingly accepted in the past decade, as a result of
new models substantiating its plausibility and new evidence that the conditions specified by …

▪ 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 …

We propose a new mechanism for diversification of male nuptial–colour patterns in the
rapidly speciating cichlid fishes of Lake Victoria. Sympatric closely related species often …

Neanderthals and Modern Humans develops the theme of the close relationship between
climate change, ecological change and biogeographical patterns in humans during the …

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 …

Several models have been proposed to suggest how the evolution of sex-determining
mechanisms might contribute to speciation. Here, we describe the inheritance of sex in 19 …
