Recent advances in resolving the tree of eukaryotes are converging on a model composed of a few large hypothetical 'supergroups', each comprising a diversity of primarily microbial eukaryotes (protists, or protozoa and algae). The process of resolving the tree involves the synthesis of many kinds of data, including single-gene trees, multigene analyses, and other kinds of molecular and structural characters. Here, we review the recent progress in assembling the tree of eukaryotes, describing the major evidence for each supergroup, and where gaps in our knowledge remain. We also consider other factors emerging from phylogenetic analyses and comparative genomics, in particular lateral gene transfer, and whether such factors confound our understanding of the eukaryotic tree.
在解析真核生物进化树方面的最新进展正趋向于一种由少数几个大型假设“超群”组成的模型，每个超群都包含多种主要为微生物的真核生物（原生生物，即原生动物和藻类）。解析进化树的过程涉及多种数据的综合，包括单基因树、多基因分析以及其他类型的分子和结构特征。在此，我们回顾了在构建真核生物进化树方面的最新进展，描述了每个超群的主要证据以及我们知识中仍存在的空白。我们还考虑了系统发育分析和比较基因组学中出现的其他因素，特别是横向基因转移，以及这些因素是否会混淆我们对真核生物进化树的理解。
