     If a population is not in Hardy-Weinberg equilibrium, we can conclude that:  evolution has occurred.  natural selection has occurred.  one of the assumptions of the Hardy-Weinberg equilibrium has been violated.  evolution has occurred because one of the assumptions of the Hardy-Weinberg equilibrium has been violated.
