The Red Queen hypothesis suggests that sexual reproduction provides protection against parasites, because it is easier for parasites to evolve means of overcoming the defenses of genetically identical clones than those of sexual species that present moving targets, and there is some experimental evidence for this.
A hipótese da Raíña Vermella indica que a reprodución sexual proporciona protección contra parasitos, porque é máis fácil para os parasitos facer evolucionar medios para superar as defensas de clons xeneticamente idénticos que as das especies sexuais que presentan dianas móbiles, e hai algunhas evidencias experimentais sobre isto.
