In biology, speciation can occur due to isolation, leading to the evolution of new species. Allopatric speciation involves geographic isolation, affecting the genetic divergence. Genetic differences post-speciation may hinder the remerging of species after environmental changes.
Speciation:
A. In smaller, separate lakes, there is a greater chance of speciation due to isolation leading to different environmental pressures.
B. If new fish species evolve from the original in small, separate lakes, it would be allopatric speciation as it involves geographic isolation.
C. If small lakes joined after speciation and flooding occurred, the fish may not become one species again due to genetic differences developed during speciation.
