TL;DR: The polymerase chain reaction was used to amplify small-subunit ribosomal DNA from the anaerobic ciliated protozoon Metopus palaeformis, and from its uncultured endosymbiotic bacteria, but the present data were insufficient to resolve the detailed relationship between Blepharisma and Metopus and thus to determine if the heterotrichs are mono- or paraphyletic.

TL;DR: The results indicate a considerable potential for physiological-biochemical plasticity among a group of predominantly aerobic eucaryotes, and provide a phylogenetic framework to further refine and test hypotheses of the origins of the hydrogenosomal enzymes.

TL;DR: It seems possible that all eukaryotes may eventually be shown to contain an organelle of mitochondrial ancestry, to which different types of biochemistry can be targeted.

TL;DR: It is possible that all eukaryotes may eventually be shown to contain an organelle of mitochondrial ancestry, bearing testimony to the important role that the mitochondrial endosymbiosis has played in eUKaryotic evolution.

TL;DR: A new molecular phylogeny is presented for the highly diverse, bivalve molluscan subclass Heterodonta, indicating that the basal clades of Crassatelloidea, Anomalodesmata and Lucinoidea diverged very early in the Lower Palaeozoic.
