Biology Question on evolution
Evolution of different species in a given area starting from a point and spreading to other geographical areas is called
A
Adaptive radiation
B
Natural selection
C
Divergent evolution
D
Migration
Answer
Adaptive radiation
Explanation
Solution
Adaptive radiation (divergent evolution) is the evolution from one species of animals or plants of a number of different forms. As the original population increases in size it spreads out from its centre of origin to exploit new habitats and food sources. In time, this results in a number of populations each adapted to its particular habitat: eventually these populations will differ from each other sufficiently to become new species.
