Variability occurs spontaneously in the course of generations, in nature as in stock-breeding. In both cases, the size of the populations plays a major role in providing the opportunities for variations to appear. This is where the time factor comes in. In itself, duration has no influence on natural selection.

Lapse of time is only so far important, and its importance in this respect is great, that it gives a better chance of beneficial variations arising, being selected, increased, and fixed, in relation to the slowly changing organic and inorganic conditions of life.61
