Examples

  • The reason of my being so much interested just at present about sexual selection is that I have almost resolved to publish a little essay on the Origin of Mankind, and I still strongly think (though I failed to convince you, and this to me is the heaviest blow possible) that sexual selection has been the main agent in forming the races of man.

  • By the way, I doubt whether the term voluntary in relation to sexual selection ought to be employed: when a man is fascinated by a pretty girl it can hardly be called voluntary, and I suppose that female animals are charmed or excited in nearly the same manner by the gaudy males.

    Alfred Russel Wallace Letters and Reminiscences

  • No doubt a slight blush adds to the beauty of a maiden's face; and the Circassian women who are capable of blushing, invariably fetch a higher price in the seraolio of the Sultan than less susceptible women. 32 But the firmest believer in the efficacy of sexual selection will hardly suppose that blushing was acquired as a sexual ornament.

    The expression of the emotions in man and animals

  • The ones that had been freed to follow female-driven sexual selection rather than predator-driven selection for individual survival had not only become more brightly coloured: in all the other respects I have just listed, these fish had evolved the full cluster of other changes, to match those normally found in wild populations free from predators.
