Question
16. Reason for diversity in a living being is due to:
- A. Mutation
- B. Gradual change
- C. Long term evolutionary change
- D. Short term evolutionary change
Solution
The diversity in living beings is due to a combination of all the options provided.
A. Mutation: This is a change in the DNA sequence that can lead to variations in traits or characteristics. Mutations can be caused by errors in DNA replication or by environmental factors such as UV radiation, chemicals, or viruses.
B. Gradual Change: This refers to the slow, steady process of evolution over a long period of time. Over generations, small changes accumulate leading to significant differences in species.
C. Long term evolutionary change: This is also known as macroevolution. It involves significant biological changes that occur in a species over a long period of time, leading to the emergence of new species.
D. Short term evolutionary change: This is also known as microevolution. It involves small-scale changes in a species' gene pool over a few generations, which may lead to variations within a species.
So, the reason for diversity in living beings is due to a combination of mutation, gradual change, long term evolutionary change, and short term evolutionary change.
