B.
Evolution of similar traits in unrelated species
C.
The extinction of a species
D.
The migration of species to new habitats
Solution
Adaptive radiation is the rapid evolution of many species from a common ancestor, often occurring when species colonize new environments with diverse ecological niches.
Correct Answer:
