Coloration is an easily quantifiable visual trait that has proven to be a highly tractable system
for genetic analysis and for studying adaptive evolution. The application of genomic …

Carotenoids exert a rich variety of physiological functions in mammals and are beneficial for
human health. These lipids are acquired from the diet and metabolized to apocarotenoids …

Synopsis “Sex” is often used to describe a suite of phenotypic and genotypic traits of an
organism related to reproduction. However, these traits—gamete type, chromosomal …

Recent adaptive radiations are models for investigating mechanisms contributing to the
evolution of biodiversity. An unresolved question is the relative importance of new mutations …

The Mediterranean basin is a hotspot of biodiversity, fuelled by climatic oscillation and
geological change over the past 20 million years. Wall lizards of the genus Podarcis are …

Sexual dichromatism, a difference in coloration between males and females, may be due to
sexual selection for ornamentation and mate choice. Here, we show that carotenoid-based …

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

Vertebrate pigmentation patterns are amongst the best characterised model systems for
studying the genetic basis of adaptive evolution. The wealth of available data on the genetic …

Differentiated sex chromosomes are believed to be evolutionarily stable, while poorly
differentiated sex chromosomes are considered to be prone to turnovers. With around 1700 …

Snakes are a remarkable squamate lineage with unique morphological adaptations,
especially those related to the evolution of vertebrate skeletons, organs, and sensory …
