qroqqa The extant mammals divide into monotremes and Theria. The monotremes are the platypus and echidnas, the Theria are the rest and divide into marsupials and Eutheria, which latter is all of us (aardvarks, horses, bats, humans etc.). The terminology can be multiplied but the important thing is the bifurcating tree: monotremes plus the rest, and the rest are marsupials plus the rest, the eutherians. Jan 27, 2009
Prolagus Being a monotreme, it's a prototherian. Jan 27, 2009
sionnach Is the platypus eutherian or metatherian? Or neither? I'm very confused. Jan 27, 2009
