Evolution, religion, and ignorance.

[RDK]

Animals that adapt to their environment over time is something that every creature has the ability to do. The unusual types and varieties of animals isolated on an island for many years shows that happening. This should be called adaptation, not evolution. Even though the appearance and habits of a group of particular animals can change over time if isolated long enough, they don't change into a different type of mating species. If one particular animal did experience a sleight change genetically, it could not mate with any of it's family to carry on the variation. The genetic similarity of animals excludes any but minor changes to the animal over time. Any changes that alter the animals ability to mate will exclude that change for future generations. That animal will not find a compatible mate.
