If you believe basic biology is not central to "diagnostic and therapeutic prinicples", I can offer you no satisfactory explanation.

As I said, YMMV.

Ok then, how is a belief in evolution necessary to the treatment of hypertension? Diabetes? Coronary artery disease?

Everything there is to know about hypertension includes thousands of basic biologic principles, but not a single one of them is evolution. Same for diabetes, coronary artery disease, insert name of disease here...

I can't think of a single diagnostic or therapeutic principle where evolution is a factor.

The flaw in your reasoning is that evolution is a RELEVANT basic biologic principle to the practice of medicine. It isn't. In any way.
