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, primarily by a 'supergene' of at least five loci. Unf...

The Rajendran-Grove (RG) ceramic damage model is a three-dimensional internal variable based constitutive model for ceramic materials, with the considerations of micro-crack extension and void collapse. In the present paper, the RG ceramic model is implemented into the newly developed computational framework based on the Meshless Local Petrov-Galerkin (MLPG) method, for solving high-speed impac...

Introduction Recently, much philosophical discussion has centered on the best way to characterize the concepts of random drift 1 and natural selection, and, in particular, whether selection and drift can be conceptually distinguished 2 These authors all contend, to a greater or lesser degree, that their concepts make sense of biological practice. So it should be instructive to see how the conce...
