Unfortunately, "the division of the Foraminifera into subgroups is problematic; existing morphology-based schemes (e.g. Loeblich and Tappan 1988) are not fully consistent with molecular phylogenetic data ... Molecular analyses reveal that polythalamous tests evolved at least twice: in the lineage leading to a large radiation of agglutinated textulariids and calcareous rotaliids, and in the lineage leading to miliolids, characterized by microgranular, low-Mg calcitic walls" (after [[BIBLIOGRAPHY|Pawlowski et al. 2003]]; from [http://www.blackwell-synergy.com/toc/jeu/52/5 Adl et al. 2005] - p.418). | !align="left" colspan="2"|Foraminiferal taxonomy is primarily based on the [[composition]] and morphology of the [[test]].
