The co-evolution of life and Earth

(Current Biology 16, R395–R400; June 6, 2006) In our recent primer, "The Co-Evolution of Life and Earth," when discussing the evolution of hydrogenosomes ("Example 2"), we accidently wrote "Recently, genetic material was extracted from the hydrogenosome of Trichomonas ovalis .." There is no organism called ‘‘Trichomonas ovalis.’’ Rather, we meant to write ‘‘Nyctotherus ovalis.’’ For more details on the evolutionary relationship between mitochondria and hydrogenosomes, we refer the reader to a recent review article on the topic by Johannes Hackstein et al., accessible online in the journal Current Genetics (DOI: 10.1007/s00299-006-0088-8).
