Line 2: − − According to creation science theories, after the Flood, marsupials bred from the Ark passengers migrated to Australia during the [[Post-Diluvian Diasporas|post-diluvian diaspora]]. There is debate whether this migration happened over land<ref name="ca1">[http://www.christiananswers.net/q-aig/aig-c006.html "How did animals get from the Ark to isolated places, such as Australia?"], ChristianAnswers.net.</ref> -- as Australia was still for a time connected to Europe by a land bridge similar to the one that connected Asia to America<ref>[http://biblicalstudies.qldwide.net.au/cs-kangaroos_dinosaurs_and_eden.html "Kangaroos, Dinosaurs, and Eden"], Ken Ham.</ref> -- or if they [[rafting (ecology) | rafted]] on mats of vegetation torn up by the receding flood waters.<ref name="ca1"/> However, if these theories are correct it is not clear why no marsupials remained in the Middle East or Europe, and instead all decided to migrate to Australia and South America. − − Another theory is that God simply generated marsupials into existence there.{{fact}}

Marsupials are mammals having a pouch (known as the marsupium, from which the name 'Marsupial' derives) in females. The pouch is used to rear its young.

[[Fossil]] evidence, first announced by researcher M.J. Spechtt in 1982, no longer supports the once-common belief that marsupials were a primitive forerunner of the [[placental mammals]]: both main branches of the mammal tree appear to have evolved at around the same time, toward the end of the [[Mesozoic]] era, and have been competitors since that time. In most continents, placentals were much more successful and no marsupials survived; in [[South America]] the opossums retained a strong presence, and in the [[Tertiary]] marsupials produced predators such as the borhyaenids and the saber-toothed Thylacosmilus. In [[Australia]] placental mammals were not present throughout much of the Tertiary and marsupials and monotremes dominated completely. Native Australian placental mammals are more recent immigrants (e.g., the hopping mice).
