HIV patients told by Pentecostal pastors 'to rely on God'

"Survival of the most adaptable" is the primary rule of evolution.

Again a less potent strain of the virus developing after a previously impervious had been established is not consistent with what you just said. Or if you prefer, a less 'adaptable' strain develops after a documented history of a pervious indestructible strain has been established is not consistent with the primary rule of evolution.

A polar bear needs thick insulation to survive in an arctic climate. If you transport a polar bear to a tropical climate, it will have to adapt many of its habits to survive, and if it reproduces (ostensibly with other, similarly-afflicted polar bears), attributes such as coloration and insulation will necessarily alter over generations to better suit the environment. This produces polar bears much less capable of surviving polar climates, not only because certain attributes making life possible in the arctic are a drawback in the tropics, but because the bears will have to come up with a different diet which is probably much lower in fat and, therefore, unable to sustain fatty insulation anyway. That's how evolution works. It can also be the result of a random mutation which leaves the organism more vulnerable in some way, but because they are lucky enough not to face the specific threat, they may pass on a lack of protection for several generations, adapting to its absence. Which may come back to hurt it later if the threat really isn't gone. Evolution does not necessarily produce improvements all the time, nor are all of its adaptations beneficial or guaranteed to work.

Evolution is far more complicated than you obviously think.
