Speciation has generated the diversity of life, yet the mechanisms of speciation remain poorly understood. Chiloglottis orchids are pollinated by highly specific sexually attracted male pollinators-an intriguing and predominantly Australian pollination mechanism. New evidence indicates these orchids offer novel opportunities to illuminate the evolutionary processes of speciation. This project will integrate new and powerful molecular laboratory procedures with field studies to investigate the mechanisms of speciation within the genus. These orchids may provide rare examples of sympatric speciation-the evolution of species in the absence of geographic isolation. This is currently a speciation mechanism of current and intense research interest worldwide.

物种形成产生了生命的多样性，但物种形成的机制仍然知之甚少。奇洛蒂斯兰花是由高度专一的性吸引雄性传粉者授粉--一种耐人寻味的、主要来自澳大利亚的授粉机制。新的证据表明，这些兰花为阐明物种形成的进化过程提供了新的机会。这个项目将把新的和强大的分子实验室程序与实地研究相结合，以研究该属内物种形成的机制。这些兰花可能提供了共域物种形成的罕见例子--物种在没有地理隔离的情况下的进化。这是目前世界范围内研究兴趣最大的物种形成机制。
