Natural rafts carried animals around the globe

According to the Bible, the only nostril-breathing, land-dwelling animals that survived the Genesis Flood were those on board Noah’s Ark. This means, that all the land vertebrates alive on the earth today must be descended from the offspring of the Ark travellers. Moreover, these must have migrated to their current habitats from the place where the Ark finally came to rest, somewhere on the mountains of Ararat, in the Middle East. Various theories have been put forward to explain how this could have happened, some of which seem quite plausible, such as migration across land bridges, which have now fallen below sea level, and transportation by humans.
Another explanation which is gaining increasing support is the rafting hypothesis.
Interestingly, the potential for dispersal of plants and animals across large stretches of water by natural rafts has been accepted by evolutionists for many years. Professor Paul Moody of the University of Vermont argued,

“In times of flood, large masses of earth and entwining vegetation, including trees, may be torn loose from the banks of rivers and swept out to sea. Sometimes such masses are encountered floating in the ocean out of sight of land, still lush and green, with palms, twenty to thirty feet [7 to 10 m] tall. It is entirely probable that land animals may be transported long distances in this manner. Mayr records that many tropical ocean currents have a speed of at least two knots; this would amount to fifty miles [80 km] a day, 1000 miles [1600 km] in three weeks.”1
More recently, the rafting idea has been advanced by evolutionists to explain the presence of the Bear Cuscus (Ailurops ursinus) and the Dwarf Cuscus (Strigocuscus celebensis) on the island of Sulawesi2 and of lemurs on the island of Madagascar.3 In 1995, fishermen witnessed the colonisation of the island of Anguilla in the West Indies by iguanas. These were washed up on one of the island’s eastern beaches, having floated there on a mat of logs and uprooted trees, a few weeks after two hurricanes hit the islands of the Lesser Antilles. Scientists believed that the iguanas had rafted 320 km from Guadeloupe.4,5
Significantly, biogeographers sometimes refer to oceans rather than continents as the main biogeographic regions. This is because, very often, patterns are seen, where many terrestrial organisms are distributed around the land bordering an ocean. So clear was this to the twentieth century biogeographer, Léon Croizat, that he spent much time drawing “tracks” to chart repetitious occurrences of these patterns.6,7 The track for Oreobolus plants, for example, is shown in fig. 1, and it is one that is shared with a multitude of other plants and animals.8,9

The destructive power of large volumes of fast-flowing water is enormous and, in the early stages of the Genesis Flood, would have been sufficient to rip-up large amounts of woodland. Although some of this would have been buried in sediments, many billions of trees would have been left floating on the surface of the waters, as enormous ‘log mats’.
These islands of vegetation, regularly watered by rainfall, could have easily supported plant and animal life over significant periods of time. Ocean currents would have moved these massive ‘rafts’ around the globe, sometimes washing them up beside land, where animals and insects might ‘embark’ or ‘disembark’, and then transporting them back out to sea. I’m not suggesting that land animals survived the Genesis Flood on rafts. Rather, these rafts would have facilitated their dispersal after the Flood, as they multiplied and migrated away from the mountains of Ararat (Genesis 8:4).
The ability of ocean currents to distribute floating objects around the world was seen recently, when thousands of bathtub rubber ducks were lost off a container ship in the North Pacific in 1992. In less than three months, these had floated to Indonesia, Australia and South America, and subsequently into the Arctic and Atlantic oceans.10,11

Interestingly, the patterns of plant and animal distribution throughout the world are not random, as might be expected from evolutionary theory. Instead, we often find many different species clustered in what biogeographers describe as “areas of endemism”—where many different plants and animals are concentrated in the same distinct and often small regions.
Moreover, and most significantly, the areas of high plant endemism generally correspond to areas of high animal endemism.12,13 This, together with the fact that there are often many floral and faunal similarities between areas of endemism14, provides strong support for the idea that the plants and animals were transported to these places—and by the same means.
Further support for the rafting theory was provided by researchers at Bryan College, Tennessee, who showed that the intersections of ocean currents with land masses appear to correspond with the areas of endemism found throughout the world.15
Explaining patterns of biogeography is difficult because the events in question all occurred many years outside of living memory. Creation scientists, however, have an advantage over other scientists, as the Bible provides a historical framework which can guide their thinking. And, as with other areas of creation research, the field data is increasingly seen to fit the biblical model better than the evolutionary model.

Readers’ comments
During the Ice Age (Pleistocene), there was probably a land bridge from Asia that almost reached Australia. So the distance that marsupials would have needed to raft to get to Australia would have been quite short. The distance from Australia to New Zealand is much greater, making this less probable.
Darwin’s theory was, from the beginning, ideologically driven, not scientifically driven, as I show here: darwin-and-lyell.
Rafting from Southern Asia to Australia may not have taken very long.
Please try to consider all possible explanations, and their logical outcomes, before decrying certainty. Cheers.
As I replied to Stephen D., we think that the division of the earth in the days of Peleg probably refers to the separation of the peoples at Babel when God confused their languages (see in-pelegs-days-the-earth-was-divided). Rapid separation of the continents in the days of Peleg would arguably have been so catastrophic as to start another global flood!
Many animals could easily have survived a few weeks on rafts, eating vegetation on the log mats and drinking water from rainfall. As Professor moody pointed out, these rafts could easily have travelled distances of 1000 miles in three weeks.
"Interestingly, the patterns of plant and animal distribution throughout the world are not random, as might be expected from evolutionary theory."
What makes you think that? I'm pretty sure evolutionary theory would predict similar animals in specific places, with gradual changes over geography, with bigger differences across bigger geographic boundaries. For instance: you'd expect to find lots of unique animals on a distantly isolated island (like Australia).
It's the flood theory that seems more likely to randomly distribute animals to me. Why don't we see Kangaroos around Turkey? They would not have had to go far from Mt. Ararat to find a hot arid environment to call home.
We also find many similarities between these regions—where the same plants and animals are distributed around or either side of an ocean. There are numerous patterns of disjunction like this, where, again and again, we find the same plants and animals in the same widely separated areas. Christopher Humphries of the Natural History Museum in London and Lynne Parenti of the Smithsonian Institution wrote,
Again this is hardly a prediction of evolution. However, since these areas of endemism appear to correspond to intersections of ocean currents with the continents, rafting may provide a good explanation.
Marsupial distributions are not explained any better in an evolutionary model than a creationist model. Marsupial fossils are found on every continent so, in evolutionary thinking, marsupials must have died out on all the continents except the ones where we find them today. Why can't creationists simply argue the same?
Some evolutionists argue that placentals tend to outcompete marsupials when they share the same habitats (which may be true). It may be that competition from placentals drove marsupials to migrate away from the Ark ahead of placentals. Perhaps marsupials then gained an early foothold in Australia and South America and, in these fairly isolated areas, and without competition from placentals, they thrived in those places.
