The evolution of colour pattern complexity: selection for conspicuousness favours contrasting within-body colour combinations in lizards.

abstract：:The tuatara (Sphenodon punctatus) is the only living representative of Rhynchocephalia, a group of small vertebrates that originated about 250 million years ago. The tuatara has been referred to as a living fossil; however, the group to which it belongs included a much greater diversity of forms in the Mesozoic. We ex...
