Genetically-based changes to these aspects of mating could complete the process of reproductive isolation and speciation. For example, bowerbirds (shown below) construct elaborate bowers and decorate them with different colors in order to woo females.

It is distinguished between prezygotic and postzygotic barriers, that foster reproductive isolation. The first type prevents fertilization and the development of a zygote, the latter is the cause of feeble or sterile hybrids.

Step 2. Reproductive isolation occurs between two populations of Ancestor Species A. ... For the sake of our example, let's assume that reproductive isolation within Ancestor Species A occurred after two units of evolutionary time had passed since the original prototype ancestral species originated.
