How did Kangaroos get to Australia?

The flood of Noah and its immediate aftermath is described in Genesis chapters six through nine. Those familiar with the story know that God determined to destroy every man and beast on the earth with a flood. Noah and his immediate family were the only humans to be saved from destruction. God instructed Noah to build a large boat in which his family and two of every animal kind (That’s not a typo. Two of every animal kind, not two of every kind of animal.) were to be saved. Noah built the ark, the heavens opened, the earth flooded and the earth was buried under the waters. A year later Noah opened the door and everyone ventured out into a very different earth. From the Middle Eastern mountains of Ararat man and animals spread across the world.

This raises many specific questions about how plants and animals could spread to every corner of the globe. How the animals spread from the Middle East across the European, African and Asian continents is easy to understand. Since a land bridge existed between Russia and Alaska it is easy to see how wildlife could reach the American continents. Australia is separated from the rest of the continents and poses a more difficult challenge.

In Genesis 10 the Bible tells a little bit about the dispersal of humanity but says nothing about the spread of plants and animals. The Bible says nothing about the continent of Australia. Does this prove the Bible is unreliable in guiding our understanding of the earth’s history? Of course not. No Christian believes the Bible teaches about every subject. Those who uphold the authority of the Bible believe that when the Bible does speak about a subject everything it says is accurate.

Starting with the premise that the Bible’s description of world events is accurate then an explanation can be formed that provides a reasonable means for kangaroos to hop to Australia. In Genesis 8:17 God commanded Noah to bring all the animals out of the ark, “that they may breed abundantly in the earth, and be fruitful, and multiply upon the earth”. God intended for wildlife to spread and multiply across the entire world. He worked in the world to fill the entire globe with all manner of wildlife.

But what about the kangaroos? How did they get to Australia? Some have suggested that animals floated to Australia on large rafts of plants and trees. The flood waters would not have buried all every piece of refuse torn up during the flood. Possibly large rafts of logs and debris were floating on the oceans of the world. Such rafts would have helped transport animals to more remote places. Others have suggested that man brought animals to Australia with him when he colonized the continent. These are both plausible suggestions, but another one seems most reasonable.

The cataclysm of the flood caused significant changes in the atmosphere and the ocean waters. These changes resulted in the ice age. During the ice age huge quantities of water were trapped in the ice sheets lowering ocean levels and exposing significant land bridges. One such bridge would have extended from southeast Asia to northern Australia and provided a thoroughfare for kangaroos to hop to Australia. While this may not be what happened, it gives a plausible explanation that lines up with what the Bible teaches. The presence of kangaroos down under does not undermine the Bible. God worked through natural mechanisms to spread animals across the globe even the funny animals of Australia.
