Marsupial evolution

FYI NJ, a platypus is a monotreme, not a marsupial. Monotremes lay eggs and have only one hole for peein', poopin', and birthin', like birds and reptiles. Also marsupials have live births, albeit much less developed than placental mammals.I would use scientific terms here but it is readily apparent you are not familiar with the literature. Edited by anglagard, : add term placental since all are mammals, would hate to be sloppy when criticizing another's sloppinessEdited by anglagard, : precision.

As best I can tell many of the folks here were students but they graduated. Some have even post-graduated multiple times and some have even managed to achieve wisdom beyond that which a formal education is meant to provide.Of course, the most intelligent posts IMO come from those who are forever both graduates and students. The real question is can you accept and describe the difference between and similarities to placental mammals that marsupials have. If you can't describe them, which is a reality, then you are neither a deserved graduate nor an accomplished student.Edited by anglagard, : clarity
