The Kaneshiro model of peripatric speciation results from sexual selection of male traits by choosy females. Here, an initial population contains males with an attractive trait that are desirable to females. When a small selection of the population becomes isolated, the sexual trait is lost and females with the preference are selected against. This gives rise to the evolution of a new trait (green), of which reproductively isolates the new population from the old.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1">[1]</a></sup>
