Sentence examples for evolutionary colour from inspiring English sources

Evolutionary colour changes dictated by shifting selection are suggested by many populations that show geographical or temporal clines (graded series of morphological characters).

Instead of being an effect of evolutionary colour signals, the new claim was that the difference in performance was due entirely to the visibility of the different colours.

Despite the large number of studies on coloration in our target species, published evidence for evolutionary significance of colours is only available for colour patches shown to be sexually selected or indicators of quality (Table 1).

Furthermore, visual predation is only one of many selective agents that influence the evolutionary dynamics of colour morph frequencies.

Our findings demonstrate that crypsis is background-dependent, and implicate visual predation as an important driver of evolutionary modifications of colour polymorphism in pygmy grasshoppers.

Our findings implicate visual predation as an important driver of evolutionary modifications of colour polymorphism in pygmy grasshoppers, and provide clear evidence that, at least in this system, see also [ 25], using humans as 'predators' in detection experiments may offer reliable information on the protective values of colour patterns and of natural selection and evolution in the wild.

These findings implicate visual predation as an important driver of evolutionary modifications of colour polymorphism in pygmy grasshoppers, and demonstrate that, in our system, using humans as 'predators' in detection experiments contributes reliable and relevant information that enhances our understanding of natural selection and evolution.

Overall, the evidence for evolutionary adaptation of shell colour to climate in Cepaea nemoralis is quite strong.

Yet, few attempts have been made to confirm that rates of detection by humans can predict patterns of selection and evolutionary modifications of prey colour patterns in nature.

There are still very few studies of the molecular basis of parallel phenotypic changes across taxa in wild plants, with one striking exception: the study of evolutionary transitions in flower colour.

Over this time scale, evolutionary change in shell colour traits appears to accumulate with a mean rate of 15 31 kDar, and Figure 5b suggests that this process has not yet stabilised.
