Question

Which of the following is am example of adaptive radiation?

Answer 1

(B) One population of lizards leads to 15 separate species over a short time

Adaptive radiation is a single species diversifying into more to suit its environment(s) 

Answer 2

Answer: The correct answer is (B) One population of lizards leads to 15 separate species over a short time.

Adaptive radiation is a process of macro-evolution in which one specific life form is rapidly diversified into another new life forms when it encounters changing environmental conditions.    

Thus, when one population of lizard leads to 15 separate species over a short time, it reflects adaptive radiation.      

Example- Darwin's finches on galapagos island, which were adapted for different feeding behavior is the example of Adaptive radiation.
