Interesting that you bring up the placental/marsupial divergence. If there was ever an actively researched and well documented evolutionary sequence, that is it. Backed by work in several areas of science, too. It's fascinating and it's all evolution. I have not seen anything using another paradigm that can explain it. Yes, the picture is not complete, but more information is coming in about the mechanisms, chronology, and changes in the genetic sequences that make these two lines different. And it's ALL evolution. No other paradigm.
