DNA of Madagascan Carnivores

DNA of Madagascan carnivores suggest they all descended from a single family that arrived by sea between 18 and 24 million years ago according to Nature, vol. 421 p734, 13th February, 2003. Madagascar has a number of apparently diverse carnivores but DNA tests reveal they are all members of a fairly tight-knit family of mongoose-like creatures that also live on the African mainland. Africa and Madagascar were once linked by a land bridge, but according to evolutionary theory, this was 26 to 24 million years ago and before the supposed mongoose ancestors evolved. The scientists who carried out the DNA study suggested the carnivores colonised Madagascar when a powerful storm blew a tree trunk containing a family of the animals across the sea. The animals could have survived the 500km journey by going into a state of semi-hibernation a characteristic still seen in Madagascan carnivores during times of food shortage.

Editorial Comment: If we ignore the millions of years, these findings also fit neatly into Biblical history. Here are two possible explanations for the above results.

1: At the time of Noah's flood at least one pair of each original created kind was preserved on the ark. After the flood these would have bred to form a family of animals which migrated into Africa, which for a time was linked to Madagascar by land bridge and some ancestral carnivores could have crossed it. When the sea levels rose again (after the ice referred to in the book of Job) they would have become isolated. Genetic diversity within the ancestral group would have emerged as the animals split up into separate inbreeding groups as they exploited the various habitats and food available to them in their new Madagascan environment.

2: The tree trunk and storm theory may also be right, but this fits Biblical history as well. Many island dwelling animals would have arrived at their present homes in such a way as they spread over the world after the flood. It is also interesting that hibernation is suggested as a means of surviving a long sea voyage Creationists have long been suggesting that as a means of enabling the Ark's creatures to survive.
