You asked why I would expect no macro changes with the “digital” DNA code. Simple, digital codes are extremely difficult to change without completely destroying their basic structure, and resulting loss of information. DNA is not analog, there are no shades of gray. On the other hand micro changes, which are changes that take advantage of variations within the code structure are obviously all around us, whether generated by natural selection or selective breeding.

The trick is differentiating between the two.

The lack of transitional forms is one of the great embarrassments of evolution. Advancements in our understanding cannot go forward until we are able to deal with this issue in a straight forward manner.

Would you characterize the difference between a mose and a rat as a micro or a macro change?

Modern evolutionary theory agrees that the vast majority of mutations result in nonviable organisms - so macro changes, as accumulations of micro mutations that are not only viable but advantageous, take a very long time.
