Question

fill in the blank question
the formation of small islands by volcanic activity and their subsequent colonization may lead to, evolution of a closely related group of species adapted to different parts of the environment.

Explanation:

Adaptive radiation is the process where organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches. In the case of small islands formed by volcanic activity, new and diverse habitats are created. As species colonize these islands, they adapt to different parts of the environment, leading to the evolution of a closely - related group of species.

Answer:

adaptive radiation
