Polar bear, Ursus maritimus Evolved by losing information. |
How did new information create polar bears?
According to creationists, it can't have done because, so the dogma says, no new information can arise due to mutations, and since evolution requires mutations on which selection can work, it should follow that evolution can't include new information. A corollary to this dogma is that loss of information is invariably detrimental.
The problem with that dogma is that real world biology keeps finding examples that shouldn't be there. The latest is the finding that polar bears evolved from a common ancestor with brown bears by adaptations that required changes in the number of certain key genes. This was discovered by researchers from the University of Massachusetts Amherst College of Natural Science.
