"In a species with a million individuals," writes John H. Gillespie, "it takes roughly a million generations for genetic drift to change allele frequencies appreciably. There is no conceivable way of verifying that genetic drift changes allele frequencies in most natural populations. Our understanding that it does is entirely theoretical. Most population geneticists are not only comfortable with this state of affairs, but revel in the fact that they can demonstrate on the back of an envelope, rather than in the laboratory, how an important evolutionary force operates."
