According to the origins theory model used by creation scientists, modern kangaroos are the descendants of the two founding members of the modern kangaroo baramin that were taken aboard Noah's Ark prior to the Great Flood. It has not yet been determined by baraminologists whether kangaroos form a holobaramin with the wallaby, tree-kangaroo, wallaroo, pademelon and quokka, or if all these species are in fact apobaraminic or polybaraminic. There is, however, no evidence of a genetic bottleneck in the kangaroo species which would be expected if all kangaroos were descended from two individuals.
After the Flood, these kangaroos bred from the Ark passengers migrated to Australia. There is debate whether this migration happened over land with lower sea levels during the post-flood ice age, or before the supercontinent of Pangea broke apart, or if they rafted on mats of vegetation torn up by the receding flood waters. The idea that God simply generated kangaroos into existence there is considered by most creation researchers to be contra-Biblical.
Other views on kangaroo origins include the belief of some Australian Aborigines that kangaroos were sung into existence by their ancestors during the "Dreamtime" and the evolutionary view that kangaroos and the other marsupials evolved from a common marsupial ancestor which lived hundreds of millions of years ago.
A majority of biologists regard evolution as the most likely explanation for the origin of species including the kangaroo.
Conservapedia, The Trustworthy Encyclopedia has Commandments rather than rules governing their work. Everything must be original, true and verifiable and no opinions are to be stated.
That said, one of the sources used for this article claims the following.
Kangaroos are ingenious examples of God’s craftsmanship, designed by a Creator who knew perfectly what He was doing. To Him all praise, glory, and honour is forever due.
That sort of stuff is right in line with the Commandments, obviously. No mention of the Ark in Wikipedia. Obviously a left wing atheist bias.
So basically Joey and Skippy, the kangaroos from the ark made their way by a series o improbable means, chosing Australia as the ideal spot to raise their family. The rest as they say, is history.
I think I will stick with the scientists.
