  • Prolagus commented on the word eutherian

    One of my best Scrabble words, built around "H-E-R". Moreover, I was playing with a group of physical anthropologists and all biology-related words got an additional 3X!

    Is the platypus eutherian or metatherian? Or neither? I'm very confused.

    Being a monotreme, it's a prototherian.

  • qroqqa commented on the word eutherian

    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.
