Local adaptation has been a major focus of evolutionary ecologists working across diverse
systems for decades. However, little of this research has explored variation at …

Parallel phenotypic diversification in closely related species is a rigorous framework for
testing the role of natural selection in evolution. Do parallel phenotypes always diversify by …

The transition from 'well-marked varieties' of a single species into 'well-defined species'—
especially in the absence of geographic barriers to gene flow (sympatric speciation)—has …

Throughout their lives animals must complete many tasks, including finding food, avoiding
predators, attracting mates, and navigating through a complex and dynamic environment …

Carotenoids are among the most prevalent pigments used in animal signals and are also
important for a range of physiological functions. These concomitant roles have made …

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 …

Studies on polymorphisms have been foundational to our understanding of evolution. The
presence of different phenotypic morphs is sometimes considered a precursor to speciation …

Animal colors play important roles in communication, ecological interactions and speciation.
Carotenoid pigments are responsible for many yellow, orange and red hues in animals …

Sympatric speciation remains controversial.'Sympatry'originally meant “in the same
geographical area”. Recently, evolutionists have redefined 'sympatric speciation'non …

Polymorphisms have fascinated biologists for a long time, but their genetic underpinnings
often remain elusive. Here, we aim to uncover the genetic basis of the gold/dark …
