LOL, from what I see of scientific advances, I don't think you quite have that right. And, I might add, from examining more about the polio vaccine, it seems apparent that Sabin and Salk had their differences. But thankfully polio has been near about eradicated. I truly don't see that examining microbes and microscopic evidences in looking for cures for polio or disease is linked with evolution. It can be linked with using microscopes and other instruments to study what is being examined. Such as tissue and cells. Science is still progressing in many ways, studies are still being done in medical fields, yet let's say things like Epstein Barr syndrome can be linked with somehow not good functioning dna. But then we have the situation of growing old and then leaving 'life.' Also in the dna. At least Dr. Salk took the vaccine himself, I haven't really read all about it. I haven't been to medical school but not sure if they teach evolution there.
