A grant has been awarded to Dr. Andrew Brower and Mr. Andrew Warren at Oregon State University to investigate the evolutionary relationships among the subfamilies and tribes of the skipper butterflies of the world (family Hesperiidae). As his dissertation research, Warren will combine DNA sequences from several different genes with morphological character data from examination of pinned adult specimens, to elucidate the pattern of relationships of this large and poorly-understood group of butterflies. The DNA part of the study will sample broadly among more than 100 genera, while the morphological component will examine a reduced set of about 50 exemplars representing the range of variation from the global fauna.As the most charismatic group of invertebrates, butterflies have served as model organisms in a broad range of evolutionary and ecological studies, and enjoy a broad constituency of amateur enthusiasts who appreciate them in various ways from collecting to photography to watching. Because they have been the subject of this attention for hundreds of years, butterflies have perhaps the most comprehensive geographical and temporal records of distribution patterns of any diverse animal taxon, which makes them excellent indicators of environmental change. Surprisingly, however, our knowledge of their evolutionary relationships is quite limited. This research represents a key component of an effort that is currently underway to develop a comprehensive phylogenetic hypothesis for all butterflies - that is, to have a complete "tree of life" for butterflies that will provide a predictive basis for future studies of the evolution of wing patterns, mimicry, aposematism, host plant coevolution, and other topics of recurrent interest in the fields of ecology and evolution.

俄勒冈州立大学的安德鲁·布罗尔博士和安德鲁·沃伦先生获得了一笔赠款，用于调查世界上跳蝶亚科和部落之间的进化关系（跳蝶科）。作为他的论文研究，Warren将结合来自几个不同基因的DNA序列和来自固定的成年标本的形态学特征数据，来阐明这个庞大而知之甚少的蝴蝶群体的关系模式。该研究的DNA部分将在100多个属中广泛取样，而形态学部分将检查一组减少的约50个样本，这些样本代表了全球动物群的变化范围。作为最具魅力的无脊椎动物群体，蝴蝶在广泛的进化和生态研究中被视为模式生物，并享有广泛的业余爱好者群体，他们以各种方式欣赏它们，从收集到摄影到观看。因为蝴蝶数百年来一直是人们关注的对象，它们可能是所有不同动物分类群分布模式的最全面的地理和时间记录，这使它们成为环境变化的极好指标。然而，令人惊讶的是，我们对它们进化关系的了解相当有限。这项研究代表了目前正在进行的一项努力的关键组成部分，即为所有蝴蝶建立一个全面的系统发育假说，即为蝴蝶建立一个完整的“生命之树”，为未来研究翅膀图案的进化、模仿、警告、寄主植物共同进化以及其他生态和进化领域中经常感兴趣的主题提供预测基础。
