Natural selection is a gradual process which favors the survival and reproduction of organisms which have better adapted to the environment.
Adaptations or traits which favor the survival of the organisms in environment keep on passing from one generation to the next and with time theses traits get inherited in the population.
For example, in the above situation herbivores with short necks die as they could not reach the leaves that were high up in the trees. In contrast, long neck favors the survival of the organisms due to which only organisms with long necks survive and reproduce. With time, only organisms were left that had long necks.
