The sloth, a very slow-moving creature, may seem to require much more time than Scripture allows to make the journey from Ararat to its present home. Perhaps its present condition is also explicable by a similar evolutionary process. However, to account for today's animal distribution, evolutionists themselves have had to propose that certain primates have traveled across hundreds of miles of open ocean on huge rafts of matted vegetation torn off in storms.6 Indeed, iguanas have recently been documented traveling hundreds of kilometres in this manner between islands in the Caribbean.7
The Bible suggests a pattern of post-Flood dispersal of animals and humans that accounts for fossil distribution of apes and humans, for example. In post-Flood deposits in Africa, ape fossils are found below human fossils. Evolutionists claim that this arose because humans evolved from the apes, but there is another explanation. Animals, including apes, would have begun spreading out over the earth straight after the flood, whereas the Bible indicates that people refused to do this (Genesis 9:1, 11:1-9). Human dispersal did not start until Babel, some hundreds of years after the Flood. Such a delay would have meant that some ape fossils would be found consistently below human fossils, since people would have arrived in Africa after the apes.8
We may never know the exact answer to every one of such questions, but certainly one can see that the problems are far less formidable than they may at first appear.9 Coupled with all the biblical, geological, and anthropological evidence for Noah's Flood, one is justified in regarding the Genesis account of the animals dispersing from a central point as perfectly reasonable.10 Not only that, but the biblical model provides an excellent framework for the scientific study of these questions.
