The metaphor of 'genomic islands of speciation'was first used to describe heterogeneous
differentiation among loci between the genomes of closely related species. The biological …

Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Unravelling the genomic landscape of divergence between lineages is key to understanding
speciation. The naturally hybridizing collared flycatcher and pied flycatcher are important …

The origin, distribution, and function of biological diversity are fundamental themes of
ecology and evolutionary biology. Research on birds has played a major role in the history …

▪ 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 …

Charles Darwin's experiences in the Galápagos Islands in 1835 helped to guide his
thoughts toward a revolutionary theory: that species were not fixed but diversified from their …

The hypothesis that ornaments can honestly signal quality only if their expression is
condition-dependent has dominated the study of the evolution and function of colour traits …

Hybrid zones have been promoted as windows on the evolutionary process and as
laboratories for studying divergence and speciation. Patterns of divergence between …

Even before the publication of Darwin's Origin of Species, the perception of evolutionary
change has been a tree-like pattern of diversification-with divergent branches spreading …
