WebJul 30, 2024 · Figure 11 shows this type of speciation among a cichlid fish population in Nicaragua. In this locale, two types of cichlids live in the same geographic location but have come to have different morphologies that allow them to eat various food sources. Figure 11. Cichlid fish from Lake Apoyeque, Nicaragua, show evidence of sympatric speciation. WebReinforcement is a process of speciation where natural selection increases the reproductive isolation (further divided to pre-zygotic isolation and post-zygotic isolation) between two populations of species.This occurs as a result of selection acting against the production of hybrid individuals of low fitness.The idea was originally developed by Alfred …
