Figure 1 The evolving Tree of Life. (A) The three domain Tree of Life, as conceived by Woese and colleagues [1]. Area in square is expanded in panel B. (B) Placement of more recently designated archaeal phyla and superphyla, as by Castelle et al. [3]. (C) Traditional placement of the branch leading to eukaryotes is shown as a dotted line. Recent work indicates that eukaryotes may instead emerge from within or at the base of the archaeal TACK superphylum [13].
