Reason of diversity in living beings : -
A
Mutation
B
Long term evolutionary change
C
Gradual change
D
Short term evolutionary change
Detailed Solution
The great diversity of living organisms arose gradually over a very long time (about 3.5 billion years) through the accumulation of variations and natural selection.
Mutation is only one source of variation; single short-term changes cannot produce such large diversity.
So the reason for diversity in living beings is long term evolutionary change.
