No doubt, as recently remarked, the definite action of changed conditions, correlated variation, and reversion have all produced their effects. But the most important consideration is that the chief part of the organisation of every living creature is simply due to inheritance; and consequently, though each assuredly is well fitted for its place in nature, many structures now have no direct relation to existing habits of life.

The foregoing remarks lead me to say a few words on the protest lately made by some naturalists, against the utilitarian doctrine that every detail of structure has been produced for the good of its possessor. They believe that

The effects of sexual selection, when displayed in beauty to charm the females, can be called useful only in rather a forced sense. But by far the most important consideration is that the chief part of the organisation of every being is simply due to inheritance; and consequently, though each being assuredly is well fitted for its place in nature, many structures now have no direct relation to the habits of life of each species. Thus, we can hardly believe that the webbed feet of the upland goose or of the frigate-bird are of special use to these birds; we cannot believe that the
