[@silver fox] so Pokemon evolve naturally at level ten or twenty, but trainers can also opt to evolve them at an earlier level with an item like an evolution shard, which can be bpught with TP. That make sense?

I know this, I am asking if they (Pokemon with only 1 evolution) naturally evolve at 10 or 20 and if Skilled trainers can still control them since its their final form.
