Dating coupling and mate selection
Further investigation of this concept, has found that it is in fact the specific trait of blue and green colour near the eyespot that seems to increase the females likelihood of mating with a specific peacock.
Mate choice is one of two components of sexual selection, the other being intrasexual selection.
Fifteen years later, he expanded this theory in a book called The Genetical Theory of Natural Selection.
Male northern cardinals have conspicuous red feathers while the females are more cryptic in coloration.
Ideas on sexual selection were first introduced in 1871, by Charles Darwin, then expanded on by Ronald Fisher in 1915.
At present, there are five sub mechanisms that explain how mate choice has evolved over time.
In other words, before an animal engages with a potential mate, they first evaluate various aspects of that mate which are indicative of quality—such as the resources or phenotypes they have—and evaluate whether or not those particular trait(s) are somehow beneficial to them.
The evaluation will then incur a response of some sort.
