Another reason to accept evolution.....

[Mystic]

Other than the fact that we see the small mutations and no giant leaps in "the design", you mean?  Not for nothing...but if you want to propose giant leaps..you;re going to need an entirely new mechanism..because that;s not how biology works.

At that point, what relevance does biology or biological data have to this hypothetical magic trick?

Fossil evidence and design in some parts of biology of creatures, I believe clearly shows, both happen. Small mutations and big leaps.  Small mutations cannot lead to all design, even if they traversed linearly because of irreducible complexity of some designs in biology.
