The current model is that evolution acts on the molecular, cellular, and genetic level, and most importantly, at the population level.

this is rare and even more difficult to understand.

basically, the genes do not generally contain blueprints but rather processes utilizing existing cellular machinery. a "mutation" can occur in a machine which will allow a propagating difference.
and there is nothing special about populations. it's merely the only way to observe most changes. gene frequencies in gene pools.
