Sequence analysis shows Amoebozoa is a monophyletic clade. Most phylogenetic trees identify it as the sister group to Opisthokonta. That is another major clade which contains both Fungi and Animals as well as some 300 species of unicellular protists. Amoebozoa and Opisthokonta are sometimes grouped together in a high-level taxon, variously named Unikonta, Amorphea, or Opimoda.
