Particular results in biology, and the methods of biologists, are *irrelevant* to the simple distinction between and acutal *theory* and a *model*. *Both* sides of the "evolution vs. creationism" story are wrong, in the same way - they confuse a description for a predictive framework. Thus religion has no predictive value, and neither does "evolution", while *natural selection* certainly does.
Since this is so simple as to be trivial, the question becomes *why* is something so simple, so universally misunderstood. THAT is a failure of biologists in particular, and the entire culture of science in general.
Yours of course is the dilettante's choice - to maintain the fake richness of theoretical ideas for the purpose of making a more satisfying reflection of yourself. Had you ever actually *worked* on a real scientific project, you might understand this.
