Most cultivated and characterized eukaryotes can be confidentlyassigned to one of eight major groups. After a few false starts,we are beginning to resolve relationships among these majorgroups as well. However, recent developments are radically revisingthis picture again, particularly (i)the discovery of the likelyantiquity and taxonomic diversity of ultrasmall eukaryotes,and (ii)a fundamental rethinking of the position of the root.Together these data suggest major gaps in our understandingsimply of what eukaryotes are or, when it comes to the tree,even which end is up.
