Question

The cichlid is a colorful fish found in freshwater lakes. There are over a thousand species of cichlid fish today. If a species of cichlid became extinct, the niche the fish filled within the ecosystem would be left open. Explain how an available niche after extinction can lead to speciation.

Answer 1

The niche available after extinction can lead to speciation because there would be an imbalance, making resources formerly occupied by extinct fishes vacant, providing the emergence of new species to take the place of the extinct species.

When does speciation occur?

Speciation can be understood as processes that lead to the formation of new species. They occur due to differences in the genome of different populations of the same species that caused reproductive isolation and, consequently, the appearance of two different species.

With this information, we can conclude that Speciation is the process of formation of new species from lineage separation events from preexisting species.
