Phylogenies of major groups of insects based on both morphological and molecular data have sometimes been contentious, often lacking the data to distinguish between alternative views of relationships. This paucity of data is often due to real biological and historical causes, such as shortness of time spans between divergences for evolution to occur and long time spans after divergences for subsequent evolutionary changes to obscure the earlier ones. Another reason for difficulty in resolving some of the relationships using molecular data is the limited spectrum of genes so far developed for phylogeny estimation. For this latter issue, there is cause for current optimism owing to rapid increases in our knowledge of comparative genomics. At least some historical patterns of divergence may, however, continue to defy our attempts to completely reconstruct them with confidence, at least using current strategies.

昆虫的古代快速辐射:系统发育分析的挑战。

基于形态学和分子数据的主要昆虫种群的系统发育有时会引起争议,通常缺乏区分关系的替代观点的数据。数据的匮乏通常是由于真正的生物学和历史原因,例如发生演化分歧之间的时间跨度较短,以及发生分歧之后的较长时间跨度,以致后续的演化变化使早期的发展方向变得模糊。难以使用分子数据解决某些关系的另一个原因是,迄今为止为系统发育估计开发的基因谱有限。对于后一个问题,由于我们对比较基因组学的了解迅速增加,目前存在乐观情绪的原因。但是,至少有一些历史上的分歧模式,
