Why do females choose mates?

For many birds and mammals, natural selection appears to favor females who choose mates that provide them with some direct benefit that will increase their fecundity, their survival or the survival of their offspring. Such benefits might include food, a safe haven or even the prospect of fewer parasites.

Do female animals fight each other?

Two females of a species could compete with each other to access food that they then use to attract mates and produce offspring. But winning mates is rarely the primary evolutionary driver for weaponry in females. ... Male weapons are also just more extreme, making them a more attractive research target.
