Abstract

Comparative analyses of multiple genes suggest most known eukaryotes can be classified into half a dozen 'super-groups'. A new investigation of the distribution of a fused gene pair amongst these 'super-groups' has greatly narrowed the possible positions of the root of the eukaryote tree, clarifying the broad outlines of early eukaryote evolution.

摘要

对多个基因的比较分析表明，大多数已知的真核生物可以被归类为六个“超级类群”。一项对融合基因对在这些“超级类群”中分布情况的新研究，极大地缩小了真核生物进化树根部可能的位置范围，厘清了早期真核生物进化的大致轮廓。
