Why do addax's have curly horns?

Addax, also known as the white antelope or screwhorn antelope, have curly horns as a result of their evolutionary adaptations to their environment. The spiral shape allows for easier maneuvering through dense vegetation and provides an advantage in combat situations during mating displays or territorial disputes. Additionally, the unique structure of their horns may help in dissipating heat, aiding in thermoregulation in their arid desert habitats.
