Comprehensive analyses of fish colorations illuminate a simple mechanism creating intricate patterns on animals. Animals exhibit a fascinating variety of skin patterns, but mechanisms underlying this diversity remain largely unknown, particularly for complex and camouflaged colorations. A mathematical model predicts that intricate color patterns can be formed by “pattern blending” between simple motifs via hybridization. Here, I analyzed the skin patterns of 18,114 fish species and found strong… Expand

Recent advances in understanding periodic patterns, like stripes and spots, the loss of patterns, and the role of cell-type diversification in generating pigmentation phenotypes are described. Expand


Blending of animal colour patterns by hybridization
It is shown that complex and camouflaged animal markings can be formed by the 'blending' of simple colour patterns, suggesting an unexplored evolutionary process by means of 'pattern blending', as one of the possible mechanisms underlying colour pattern diversity and hybrid speciation. Expand
The periodic coloration in birds forms through a prepattern of somite origin
This work shows that the periodic striped pattern visible in juvenile birds of the galliform group, in which longitudinal stripes are organized in a black-yellow-black sequence in the dorsal region, results from the timely production of yellow coloration at specific locations. Expand
The biology of color
A roadmap of technological advances and key questions for the future of animal coloration research are provided, to identify hitherto unrecognized challenges for this multi- and interdisciplinary field. Expand
Specifying and Sustaining Pigmentation Patterns in Domestic and Wild Cats
A two-stage model in which Taqpep helps to establish a periodic pre-pattern during skin development that is later implemented by differential expression of Edn3 is proposed, which support a common model for coat and pigment pattern formation in domestic and wild cats. Expand
Developmental mechanisms of stripe patterns in rodents
It is shown that, in the African striped mouse (Rhabdomys pumilio), periodic dorsal stripes result from underlying differences in melanocyte maturation, which give rise to spatial variation in hair colour. Expand
Generation of a novel wing colour pattern by the Wingless morphogen
It is shown that wing spots are induced by the Wingless morphogen, which is expressed at many discrete sites that are specified by pre-existing positional information that governs the development of wing structures. Expand
Zebrafish Pigment Pattern Formation: Insights into the Development and Evolution of Adult Form.
What is known about lineages and molecular interactions required for pattern formation in zebrafish are summarized, some of what is known is reviewed about pattern diversification in Danio, and how patterns in more distant teleosts may have evolved to produce a stunningly diverse array of patterns in nature is speculated.

patternize: An R package for quantifying colour pattern variation.
It is demonstrated that patternize can be used for quantification of the color patterns in a variety of organisms by analyzing image data for butterflies, guppies, spiders and salamanders. Expand
Zebrafish Stripes as a Model for Vertebrate Colour Pattern Formation
Colour patterns are prominent features of many animals and have important functions in communication, such as camouflage, kin recognition and mate choice. As targets for natural as well as sexualExpand
Correlated Evolution of Female Mating Preferences and Male Color Patterns in the Guppy Poecilia reticulata
Male traits and female preferences appear to be evolving in parallel in guppy populations, and in a comparison of seven populations, the degree offemale preference based on orange is correlated with the population average orange area. Expand
