Define genetic information.

Then define how it is added and then subtracted.

I'd bet very few ID people have ever done so in a meaningful and scientific way. We're getting back to that territory where one has to ask, Define the Theory of Intelligent Design? And then wait indefinitely for an answer that invariably never comes.

Define genetic information. Then define how it is added and then subtracted.

And note that Spetner's claim that "mutations can't don't information" rests upon a extremely, um, unusual definition of "information" which only Spetner subscribes to, so if DittoJed2's source is Spetner, it's going to be a fun ride.

Genetic information is what is within the genetic material of an organism that causes it to be what it is. For example, within the genes of a dog is information that causes it to specifically be of the class, genus, and species that it is. For it to become something completely different, new genetic information would have to be added to its system. You can make it become a different variety of dog, but it is always going to be a dog. You can't introduce "cat" into it and make it become more cat-like. And you certainly don't see this kind of added information in the historical record of species. Evolution of the MACRO kind has never been observed. It is a hypothesis.
