Female rats do however show preferences for particular males) Natural selection vs. sexual selection theories attempt to explain why members of a species engage in certain behaviors or possess certain physical characteristics found attractive by mates Natural selection theories (Darwinian) emphasize that traits or behaviors are acquired inorder to increase the survivability of offspring 3 competing views: 1) good-genes theory- suggests that females benefit by mating with particular males having traits that enhance survivorship, thereby imparting these benefits to her young.
