title: Eukaryotic evolution: getting to the root of the problem.
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.
