Abstract
Berg et al. (Reports, 14 December 2007, p. 1782) reported the discovery of an autotrophic carbon dioxide-fixation pathway in Archaea and implicated a substantial role of this pathway in global carbon cycling based on sequence analysis of Global Ocean Sampling data. We question the validity of the latter claim.
