Battle of the Sexes

In the battle to ensure their genes get passed on successfully to future generations, fire ants have devised a unique strategy. Both males and females, reproduce by cloning themselves. They do engage in sexual reproduction, but all they produce are sterile worker ants. This adaptation has led to the question of whether the females and males should be considered separate species that are simply dependent on each other. Just goes to show you -- nature has quite the imagination.
