These and other studies confirmed that substantial genetically based adaptive genetic change can indeed occur in contemporary time. Drawing on examples such at these, Endler's () book Natural Selection in the Wild clearly established for the first time that evolution by natural selection was a potent ongoing phenomenon. He reviewed enough (Later studies have shown that hunting efficiencies are dependent on a variety of ecological factors, including the size and capabilities of the prey.) In the highly social African wild dog (Lycaon pictus), overall kill probabilities in hunting forays were found to be greatly superior (between 85 and 90 percent) to those achieved by less social

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.
