Are network motifs the spandrels of cellular complexity ? Ricard

need to be borne in mind (Box 1), a quantitative genetic framework has much to offer in terms of our understanding of similar problems in evolutionary ecology, because it offers a simple, coherent way to combine measured selection and expected response. This is likely to prove evenmore the case as the influence of genomics is felt ever more strongly in organismic biology (e.g. [4,16]). For example, the question of genetic linkage between male trait, female choice and fitness in wild populations could be addressed using existing genetic mapping approaches, which have already been applied, at least as proof of concept, to wild birds [17,18].
