Population genetics studies the different "forces" that might lead to changes in the distribution and frequencies of alleles -- in other words, to evolution. Besides selection, these forces include genetic drift, mutation and migration.In other words, Richard Dawkins' repeated refrain, "Evolution by Natural Selection" isn't current any more, as I'd thought.
Those who find evolution convincing need to rethink it a lot more carefully because the evidence is really not there to the extent you think it is. I suspect you are accepting as evidence all sorts of assumptions, speculations and hypotheses that are not evidence, and are taking most of it on faith in spite of yourself.
