Quizplus · Accepted Answer

Sympatric speciation occurs when new species evolve from a single ancestral species while inhabiting the same geographic region. In Lake Victoria, the rapid diversification of cichlid fish species in the same lake environment is a classic example of sympatric speciation, where different species evolved due to variations in mating preferences, habitats, and feeding strategies without geographical separation.
