The proof given by Wright, that non-adaptive differentiation will occur in small populations owing to "drift," or the chance fixation of some new mutation or recombination, is one of the most important results of mathematical analysis applied to the facts of neo-mendelism. It gives accident as well as adaptation a place in evolution, and at one stroke explains many facts which puzzled earlier selectionists, notably the much greater degree of divergence shown by island than mainland forms, by forms in isolated lakes than in continuous river-systems.

Julian HuxleyAs political and economic freedom diminishes, sexual freedom tends to compensatingly increase and the dictator... will do well to encourage that freedom in conjunction with the freedom to daydream under the influence of dope, movies, and radio. It will help to reconcile his subjects to the servitude which is their fate.
