By adopting a massively parallel tag sequencing strategy, we show that bacterial communities of  deep water masses of the North Atlantic and diffuse flow hydrothermal vents are one to two orders of magnitude more complex than previously reported for any microbial environment. A relatively small number of different populations dominate all samples, but thousands of low-abundance populations account for most of the observed phylogenetic diversity. This “rare biosphere” is very ancient sea  andmay represent a nearly inexhaustible source of genomic innovation. Members of  the underexplored  rare biosphere are highly divergent from each other and, at different times in earth's history, may have had a profound impact on shaping planetary processes.},  url = {http://www.pnas.org/content/103/32/12115.abstract},  eprint = {http://www.pnas.org/content/103/32/12115.full.pdf}, biosphere}},  journal = {Proceedings of the National Academy of Sciences},  }
