Organic evolution would not have taken place if

Options

A. Individual in a population did not show genetic varation
B. Individuals did not transmit the characters acquired during their lifetime to offsprings
C. Somatic variations were not inherited
D. Somatic variation were not transformed into genetic variations

Answer

### Step-by-Step Solution:

1. **Understanding Organic Evolution**: Organic evolution refers to the process through which species change over time through mechanisms such as natural selection, genetic variation, and adaptation to the environment.

2. **Identifying Conditions for Evolution**: For organic evolution to take place, certain conditions must be met. These include:
- The presence of genetic variation within a population.
- The struggle for existence due to environmental pressures (e.g., scarcity of resources, natural calamities).
- The ability of organisms to adapt to their environment.

3. **Recognizing Factors that Prevent Evolution**: Organic evolution would not occur under specific conditions:
- If there is no genetic variation among individuals in a population, there would be no traits for natural selection to act upon.
- If the environment is stable and does not impose any challenges or pressures, there would be no struggle for existence, leading to no need for adaptation.
- If organisms are perfectly adapted to their environment and there are no changes in that environment, evolution would not take place.

4. **Conclusion**: Therefore, organic evolution would not have taken place if there is a lack of genetic variation, absence of environmental pressures, or if the environment remains unchanged.
