Abstract

types, that disruptive selection can lead to divergence and even speciation because intermediate forms match neither substrate effectively and are selected against [17]. Interestingly, parasitic cuckoos show higher rates of speciation than non-parasitic species [20], and this may occur if different host races no longer interbreed if this breaks up sophisticated egg mimicry and other host species-specific specializations. Such processes could start to arise in ground nesting birds too if individuals start to specialize on particular distinct microhabitats. Clearly, camouflage is much more than simply a wonderful example of evolution; it can tell us a great deal about the optimization of phenotype and behaviour, macro-and micro-evolutionary processes, and mechanisms such as molecular biology and visual perception.
