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'.
This would pose a serious problem when genomes are compared. The DNA of the tasmanian wolf is much more like that of kangaroos than it is the placental wolf. This is true of all marsupials. Creationists would have to agree that microevolution is capable of producing genetic distances several fold higher than that seen between humans and chimps.
