Evidence for contrasting modes of selection at interacting globin genes in the European rabbit (Oryctolagus cuniculus).

abstract：:Echinoderms represent a researchable subset of a dynamic larval evolutionary cosmos. Evolution of echinoderm larvae has taken place over widely varying time scales from the origins of larvae of living classes in the early Palaeozoic, approximately 500 million years ago, to recent, rapid and large-scale changes that ha...
