  • Abstract Sexual differences in morphology can evolve by sexual selection and/or natural selection. In some species, only males have morphological structures that are used as weapons. Since some weapons may also be used for defensive purposes, males and females may behave differently towards predators. In some species of harvestmen (Arachnida and Opiliones), males have sharp apophyses (“spines”) on their 4th pair of legs whereas females lack them. Those apophyses are used in male–male fights and… CONTINUE READING
