Why do harmless butterflies look so like distasteful ones? Punnett lays out Batesian and Müllerian mimicry, surveys the mimics of the Old World and the New, and works through test cases such as the swallowtail Papilio polytes, asking whether the resemblances arose slowly by selection or as sudden hereditary sports.
Short and well illustrated, it shows early genetics wrestling with natural selection, and will delight naturalists and butterfly lovers. Download the free EPUB.
