Critics of science like to ridicule forensic sciences like geology and paleontology as inventing "just so" stories. What they fail to understand is the iterative process of telling the story, working out the necessary context of the story, and searching for supporting evidence.
You don't build fundamental paradigms like evolution overnight from deductive reasoning. You build it year by year, decade by decade, from speculation to evidence to refined speculation.
There is a difference between inductive and deductive reasoning, but one can pick that up pretty quickly if they are smart enough.
Though no doubt you only truly learn inductive reasoning by doing it a lot via science class.
