A brief note concerning archaebacterial phylogeny

G. J. Olsen, C. R. Woese

Research output: Contribution to journalArticlepeer-review


Critical analysis of the recently proposed alternative to the normal archaebacterial tree, the new eocyte tree, shows that the latter's central topology, in which the eubacteria branch from an entirely different section of the unrooted archaebacterial tree than the eukaryotes, is consistent with an artifact. The effects of the alignment used and the particular composition of the sequence quartets analyzed to infer this tree are discussed in detail.
