Coevolution of coloration and colour vision?

Coevolution of coloration and colour vision?

The evolutionary relationship between signals and animal senses has broad significance, with potential consequences for speciation, and for the efficacy and honesty of biological communication. Here we outline current understanding of the diversity of colour vision in two contrasting groups: the phylogenetically conservative birds, and the more variable butterflies. Evidence for coevolution of ...

Colour-Vision and Colour-Blindness

Attractive blue-green egg coloration and cuckoo-host coevolution

Recent evidence suggests that blue-green coloration of bird eggshells may be related to female and/or egg phenotypic quality, and that such colour may affect parental effort and therefore the nutritional environment of developing nestlings. Here we suggest that these relationships and the signal function of eggshell coloration would affect the outcome of coevolution between avian brood parasite...

Colour vision

The immense range of colours that we see belies the relative simplicity of the system underlying colour vision. We see colours because each of the three distinct types of cone photoreceptor in our retinae is sensitive to a different range of wavelengths of light. The L, M and S cones, colloquially called red (R), green (G), and blue (B), are selective for long, middle and short wavelengths, res...

Colour vision

Editorial Colour vision 2006 is an important bicentenary for the Ulster Medical Society. In 806, the Belfast Medical Society was founded and the later formation of the Belfast Clinical and Pathological Society in 853, allowed amalgamation of both societies to form the current Ulster Medical Society in 862. The vision of the early founders of the Belfast Medical Society, was far sighted, and som...
