... another question for creationists at large: How to explain substantial segments of genes within our own human DNA that appear to have been "switched off"

There are several creationist-style replies:

1. It's a miracle.
2. Define what you mean by "switched off"
3. You have no proof.
4. No one has ever observed a goldfish turn into a duck.
5. Marx [or Hitler, or Osama] was a Darwinist.

6. All your evidence is faked by a cabal of atheist materialists.

6) All variation we see today was stored in our genome. You are looking at tomorrow's variation.

7) All things work together for good...

And in three short posts we have a summation of arguments. Remarkable! :)
