Tracing the Fate of the Animals that Survived the Post-Flood Extinction

In our previous posts, we observed that Noah took a few thousand animals on board the Ark about 4,500 years ago. Of the kinds that stepped off the Ark, most went extinct. In mammals, for example, around 70% of the kinds are now extinct. But approximately 30% survived.

What Happened to Them?

In short, the mammals and other kinds migrated away from where the Ark landed in the mountains of Ararat. Surprisingly, in 1859 when Darwin wrote On the Origin of Species, the phenomenon of migration would have been controversial. In fact, Darwin had to corral several lines of evidence to demonstrate to his opponents that animals did indeed migrate to their current locations. Unlike Darwin’s opponents of 1859, creationists today would agree with Darwin's conclusion that migration explains the distribution of modern species.

Furthermore, creationists of the present era would freely invoke an Ice Age following the Flood. An Ice Age would effectively move large amounts of water from the oceans (liquid form) onto the land (in the form of ice). As a consequence of this directional movement, the ocean levels would drop, exposing land bridges that are currently submerged.

For example, during the Ice Age, the Bering Strait would have been crossable on foot. Conversely, in Southeast Asia, you could nearly walk from Thailand to Australia. These and other land bridges would have made migration away from Ararat to distant locations all the easier.

However, Darwin's evidence in favor of animal migration was at the level of species, not families. As we derived in one of our previous posts, the kinds on board the Ark were not individual species but, rather, representatives of various biological families. How could Darwin's point be relevant to our purposes?

New Species from Ark Kinds

Today, many biological families contain numerous species, implying that new species have arisen since the Flood. Since Scripture never forbids speciation, nothing in the Bible suggests that the formation of new species within a kind is impossible. Thus, speciation within kinds is perfectly compatible with Genesis and with the rest of Scripture.
