Little is known about the presence of incomplete convergence in the evolution of vertebrate taxa, as it is difficult to differentiate between evolutionary methods responsible for the appearance of similar forms. Grossnickle et al. present the first study of convergence evaluating all six extant glider clades using phylogenetic comparative methods. The authors find that the unique skeletal morphology of extant glider species (i.e., longer and thinner limbs) results from incomplete convergence under Brownian motion.

摘要：不完全收敛驱动滑翔机的形式函数关系

关于脊椎动物分类群进化中存在不完全收敛的情况知之甚少，因为很难区分导致相似形式出现的进化方法。Grossnickle 等人。介绍了使用系统发育比较方法评估所有六个现存滑翔机进化枝的收敛性研究。作者发现现存滑翔机物种的独特骨骼形态（即更长更细的肢体）是布朗运动下不完全收敛的结果。
