翅膀的形状可以很好地预测对不同选择压力的适应，并且翅膀特征在分类学和生殖学中的价值早已被认识到。在我们的调查后翅进化的金龟子（金龟亚科），我们使用几何形态测量学结合支序方法。利用19个标志点和轮廓数据，研究了80种蜣螂的整个后翅和3个特定区域的变异。大量的证据表明，机翼作为一个整体和三个独立的区域是在不同的选择压力。详细的进化模式的三个地区和祖先的形式重建计算的几何形态测量数据映射到一棵树的基础上的分支特征分析。(C)2012爱思唯尔有限公司保留所有权利。
The shape of wings can be a good predictor of adaptations to different selective pressures and the value of wing features in taxonomy and phylogeny has long been recognized. In our investigation of the hind wing evolution of dung beetles (Scarabaeinae) we use geometric morphometrics combined with a cladistic approach. The variations of entire hind wings and of three specific regions of 80 dung beetle species were investigated using 19 landmarks and outline data. Extensive evidence indicates that the wing as a whole and the three separate regions were under different selective pressures. The detailed evolutionary patterns of the three regions and the reconstruction of the ancestral forms were computed by mapping the geometric morphometrics data onto a tree based on a cladistic character analysis.
