The group Metatheria (Didelphimorphia) has relevance among mammals, particularly related to reproduction aspects, as they represent an important transition link between Prototheria and Eutheria groups.
However, current views give considerable support for recognizing three separate groups of living mammals, the basal lineage represents the Monotremata in Prototheria, and the derived sister groups are the marsupials in Metatheria and the placentals in Eutheria.
However, new studies have shown that older lineages of mammals (Metatheria and Prototheria) retain additional classes (AQP13 and -14) (Finn and Cerda, 2011; Finn et al., 2014).
