fill in the blank
Sexual selection is a type of blank. Sexual selection refers to an organism's ability to obtain a mate. Selection makes many organisms go to extreme lengths to attract a mate: peacocks maintain elaborate tails, blank fight over territories, blank perform dances. Going to even more extreme lengths, the male redback blank flings itself into the jaws of death in order to mate successfully. Sexual selection is powerful enough to produce features that are harmful to the individual's survival. For example, the colorful tail feathers of the peacock are likely to attract blank as well as interested mates.
