There would be no evolution if :

Options

A. The inheritance of acquired characters did not take place
B. Somatic variations were not inheritable
C. Genetic variations were not found among members of population
D. Somatic variations would not transform into germinal variations

Answer

**Step-by-Step Solution:**

1. **Understanding Evolution**: Evolution is defined as the process through which species undergo changes over generations. These changes can be in physical traits or genetic makeup, which may enhance the organism's ability to survive in its environment.

2. **Role of Genetic Variation**: For evolution to occur, there must be genetic variation within a population. This variation arises from mutations, which are changes in the genetic material. If all individuals in a population were genetically identical, there would be no basis for natural selection to act upon, and thus no evolution.

3. **Inheritance of Traits**: The traits that arise due to genetic variations must be inheritable. If traits acquired during an organism's lifetime (somatic variations) cannot be passed to the next generation, they do not contribute to evolutionary change.

4. **Importance of Mutations**: Mutations are the primary source of genetic variation. They can lead to beneficial traits that improve survival and reproduction. If mutations did not occur or if they were not beneficial, there would be little to no evolution.

5. **Conclusion**: Therefore, if genetic variations were not found among members of a population, evolution would not take place. This is because without variation, there would be no differences for natural selection to act upon, leading to stagnation in the evolutionary process.

**Final Answer**: There would be no evolution if genetic variations were not found among the members of the population.
