Visual opsin genes expressed in the rod and cone photoreceptor cells of the retina are core
components of the visual sensory system of vertebrates. Here, we provide an overview of the …

The world in color presents a dazzling dimension of phenotypic variation. Biological interest
in this variation has burgeoned, due to both increased means for quantifying spectral …

The hundreds of cichlid fish species in Lake Malawi constitute the most extensive recent
vertebrate adaptive radiation. Here we characterize its genomic diversity by sequencing 134 …

The visual pigments of vertebrates evolved about 500 million years ago, before the major
evolutionary step of the development of jaws. Four spectrally distinct classes of cone opsin …

The jawless fish that were ancestral to all living vertebrates had four spectral cone types that
were probably served by chromatic-opponent retinal circuits. Subsequent evolution of …

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 …

Tuning the visual sensory system to the ambient light is essential for survival in many animal
species. This is often achieved through duplication, functional diversification, and/or …

Among vertebrates, teleost eye diversity exceeds that found in all other groups. Their
spectral sensitivities range from ultraviolet to red, and the number of visual pigments varies …

In craniates, opsin‐based photopigments expressed in the eye encode molecular 'light
sensors' that constitute the initial protein in photoreception and the activation of the …

The turbot is a flatfish (Pleuronectiformes) with increasing commercial value, which has
prompted active genomic research aimed at more efficient selection. Here we present the …
