which of the following is an example of adaptive radiation?\none population of squirrels becomes two separate species over a long time.\none population of lizards forms 15 separate species over a short time.\none species of birds becomes better suited to its environment over time.\none species of fish forms when two species of fish begin to breed with each other.
Answer
Brief Explanations:
Adaptive radiation is the process by which 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. A population of lizards forming 15 separate species over a short time is a classic example as it shows rapid speciation and diversification.
Answer:
One population of lizards forms 15 separate species over a short time.
