Unibacteria was divided into phyla <a href="/wiki/Archaebacteria" class="mw-redirect" title="Archaebacteria">Archaebacteria</a> and <a href="/wiki/Posibacteria" class="mw-redirect" title="Posibacteria">Posibacteria</a>; the bimembranous-unimembranous transition was thought to be far more fundamental than the long branch of genetic distance of Archaebacteria, viewed as having no particular biological significance. </p><p>Cavalier-Smith does not accept the requirement for taxa to be <a href="/wiki/Monophyly" title="Monophyly">monophyletic</a> ("holophyletic" in his terminology) to be valid. He defines Prokaryota, Bacteria, Negibacteria, Unibacteria, and Posibacteria as valid <a href="/wiki/Paraphyly" title="Paraphyly">paraphyla</a> (therefore "monophyletic" in the sense he uses this term) taxa, marking important innovations of biological significance (in regard of the concept of biological <a href="/wiki/Ecological_niche" title="Ecological niche">niche</a>). </p><p>In the same way, his paraphyletic kingdom Protozoa includes the ancestors of Animalia, Fungi, Plantae, and Chromista. The advances of phylogenetic studies allowed Cavalier-Smith to realize that all the phyla thought to be <a href="/wiki/Archezoa" title="Archezoa">archezoans</a> (i.e. primitively amitochondriate eukaryotes) had in fact secondarily lost their mitochondria, typically by transforming them into new organelles: <a href="/wiki/Hydrogenosome" title="Hydrogenosome">Hydrogenosomes</a>. This means that all living eukaryotes are in fact <a href="/wiki/Metakaryote" class="mw-redirect" title="Metakaryote">metakaryotes</a>, according to the significance of the term given by Cavalier-Smith. Some of the members of the defunct kingdom <a href="/wiki/Archezoa" title="Archezoa">Archezoa</a>, like the phylum <a href="/wiki/Microsporidia" title="Microsporidia">Microsporidia</a>, were reclassified into kingdom <a href="/wiki/Fungi" class="mw-redirect" title="Fungi">Fungi</a>. Others were reclassified in kingdom <a href="/wiki/Protozoa" title="Protozoa">Protozoa</a>, like <a href="/wiki/Metamonada" class="mw-redirect" title="Metamonada">Metamonada</a> which is now part of infrakingdom <a href="/wiki/Excavata" title="Excavata">Excavata</a>. </p><p>Because Cavalier-Smith allows <a href="/wiki/Paraphyly" title="Paraphyly">paraphyly</a>, the diagram below is an

Prokaryota have two kingdoms: <a href="/wiki/Bacteria" title="Bacteria">Bacteria</a> and <a href="/wiki/Archaea" title="Archaea">Archaea</a>.
