How about Newton's derivation of Kepler's laws of planetary motion, using
as premises the law of gravitation, the second law of motion, and whatever
mathematical axioms are needed for the calculus involved?
Another example, drawing on less technically demanding mathematics (if any
at all) would be the deduction underlying the central Darwinian insight.
This is the insight that whenever the three conditions
hold ofr a population of self-reproducing entities, there will be
(Note that this is the case even if the individuals never die.)
