But the females evolve defenses to that, allowing them to survive longer.

This finding suggests a chase-away sexual selection, in which "females evolve resistance to male ploys".

To correct this imbalance, mammalian females have evolved a unique mechanism of dosage compensation.

This leads to antagonistic co-evolution, as the female must evolve in order to defend herself.

So females evolved to prefer the loud chuck that so appeals to bats.

It seems that males tend to force themselves on females, and females have been evolving convoluted reproductive passages in order to thwart them.

Its presence suggests that females may evolve ornaments of their own even when the pressure of finding a mate lies mostly on the male.

In these societies, females may evolve promiscuous behaviour, to cloud the identity of their offspring and prevent such attacks.

There are many methods that females have evolved over time to "defend" themselves against the onslaught of potential mates.
