My favorite "doozy"

Science answer: they evolved there.
Creationist answer: ? (careful - I've heard some doozies)
Just found and read through this older thread, and wanted to share one of my favorites from the Northwest Creation Network as I hadn't seen it presented here. While I can give the author some credit for originality, I do want to caution that reading the article while consuming liquids could result in damage to keyboard and moniter. Here is the link: Marsupial Evolution and Post Flood Migration
The author, Chris Ashcraft, suggests that the famous examples of placental/marsupial "twins" (thylacine/wolf, marsupial mole/golden mole, etc.) are actually the result of the original placental 'baramin' evolving pouches after they arrived in Australia. So the marsupial mole is of the same 'kind' as the placental mole, they just (through God-given genetic plasticity) adapted to Australia's harsh climate by micro-evolving a pouch. As did all of the other marsupials in Australia that are analogs of placental 'kinds'.
Some explanation:
Chris Ashcraft writes:
At times when survival has become difficult and the death rates of mothers and children are high, the marsupial mode of reproduction may prevent high mortality rates from affecting the death of the other. Under severe environmental stress when giving birth earlier becomes advantageous for the success of the population, then the marsupial reproductive mode may be selectable from the natural variation that exists within the timing and developmental rates of these events.
And this gem:
Likewise not all marsupials have a permanent pouch and a few have none at all. There is clearly natural variability of the features which distinguish the placentals from marsupials. These variations are produced by genetic recombination, and performed in attempt to specialize the organism to specific conditions. The presence of variability within the features that distinguish the placental from marsupial suggests the ability to change from one mode to another. Although many modifications would be required, in particular those that alter the gestation rate, placental and pouch development have been established as active.
And, of course, no good hypothesis can exist without a plausible cause:
It could therefore be proposed that the marsupial reproductive system can evolve from the placental method, and has done so numerous times during the evolutionary history of mammals. One possible factor effecting all who passed into Australia would be the equatorial crossing following their release from the ark in Turkey. The mammals which arrived in Australia would have been the first to cross the equator, and probably when environmental extremes were exceptional. It is possible that this evolutionary adaptation can be forced upon animals during times of severe stress or when mother/offspring mortality reaches high frequencies
Before we dismiss this hypothesis too quickly, it is important to take into consideration the effects crossing the equator could have. I think it stands as a point of historical fact that crossing the Galactic Barrier caused Lieutenant Commander Gary Mitchell to develop extreme psychic abilities...
Just a note: I recognize that this is by no means the mainstream creationist viewpoint, I just thought it topical.
