Genetic drift affects the genetic makeup of the population but, unlike natural selection, through an entirely random process. So although genetic drift is a mechanism of evolution, it doesn't work to produce adaptations.
Another important small population effect is known as the founder principle or founder effect. This occurs when a small amount of people have many descendants surviving after a number of generations. The result for a population is often high frequencies of specific genetic traits inherited from the few common ancestors who first had them.
