Question

Reason of diversity in living being is

• A. Mutation
• B. Long term evolutionary change
• C. Gradual change
• D. Short term evolutionary change

Answer 1

The correct option is B

Long term evolutionary change

The organisms which are provided with favourable variations would survive because they are the fittest to face their surroundings, while the unfit ones are destroyed. Darwin considered that useful variations are transmitted to the offspring and appear more prominently in succeeding generations. After some generations, these continuous and gradual variations in the subsequent generations would be so distinct that they form new species.
