Selecting a mate, what may seem to some to be a daunting task. Do we really have a choice in who we are attracted to? Is there a science behind reeling in the right fish for you? Indeed there is, and it is called sexual selection.
Sexual selection is when one sex selects and individual from the other sex for the purpose of mating, based on certain traits. One important element of mate value is the physical attractiveness one finds in another or what one person's characteristics makes her or him desirable to another person as a partner. Some may have their own mental check lists that incorporate the idea of mate value, perhaps a top 10 "needs to be" index that includes all necessary qualities one would require in order to make the cut. In addition, the Good Gene Hypothesis states that beauty signals deciphers if a person has good genes for intelligence, healthy babies, a good immune system, and good parenting. Individuals either end up selecting partners with high mate value OR do not select partners with low mate value.
