Alright.. I’ll bite.
For the most part, Creationists do realize there are changes in not only viruses, bacteria and the like, but certain species change as well. Otherwise the animal kingdom would not be so diverse. Everything from the environment to intermarriage and birth defects have had thousands of years to mutate varying species. There is, however no evidence of one species evolving into another.
Now when the swine flu evolves into say an airplane, a block of cheddar cheese or a tuba I’ll concede the argument.
What do you think of cross-species migration of genetic material?
