He reviewed enough @. Studies on the classic shell colour and banding polymorphism of the land snail Cepaea played a crucial role in establishing the importance of natural selection in maintaining morphological variation.

Cepaea is also a pre-eminent model for ecological genetics because the outward colour and banding phenotype is entirely genetically determined,For example, studies of shell pigmentation polymorphism in the landsnail Cepaea nemoralis showed that in some types of habitat where avian predators are an important agent of mortality, the more cryptic phenotypes are fitter, as might be expected (Cain and Sheppard ).African Studies American Studies Ancient Near East and Egypt Art History Asian Studies Book History and Cartography Biblical Studies Classical Studies Education History Jewish Studies Literature Investigation of the Synthesis and Distribution of Fatty Acids in the Lipids of the Snail Cepaea ?lang=en.
