Mate choice is choosing mates based on specific criteria where we see benefits through direct ways usually seen through material “goods” like food, nesting materials, and more. Some indirect benefits we see is usually genetic, but fall into a few hypothesis…

The first hypothesis is the “good genes” hypothesis. This hypothesis states that the traits chosen increase the viability of offspring increasing survival/reproductive success. This is usually seen in Pronghorns as the females choose males independently and offspring are more likely to survive to 5 years.

The next hypothesis is “Zahavis” handicap hypothesis. This hypothesis states that traits chosen indicate individuals ability to overcome adverse conditions. This can be seen in a peacocks tail as it might be costly, but increases the chances to females.

The last hypothesis is called Runaway selection or better known as “sexy sons” hypothesis. This states the trait and preference are correlated. Usually this is seen by females choosing the more attractive partner.

I’ve experienced mate choice on quite a few number of occasions. The one that stood out to me the most was peacocks. The males would flaunt their big feathers and even have mating calls in order to try and win over the females. Sometimes it worked, and sometimes it did not, but this goes hand in hand with “Zahavis” handicap hypothesis. Even though there is a cost of survivability with the big colorful feathers, we see an increase in mating with females. Also, peacocks are one of the most annoying creatures at night with their mating calls when you’re trying to sleep…
