The code that is DNA

What, exactly, is about testability, John?  We haven't needed to reference a single untestable thing thusfar.

For you, Yukon...we already discussed this pages ago.  Any offspring of a fruit fly will be a fruit fly.  This is not an objection to biology, it's an affirmation of biology.

It’s also an affirmation that macro evolution is a fantasy

What you are saying here is that you don't understand evolution. That's ok. We can educate you.

You are expecting a hard line in the sand. Its a common trait of people with limited understanding, but the truth is more a subtle more gradual. 

What it comes down to is small changes, over time, lead to big changes. And of course many small changes can be happening at the same time.
