Specific diversification represents `:`

Options

A. mutation
B. megaevolution
C. microevolution
D. macroevolution is greatly influenced by mass extinctions and evolutionary radiations

Answer

To solve the question "Specific diversification represents:", we will analyze each option provided and determine which one correctly corresponds to the concept of specific diversification.

### Step-by-Step Solution:

1. **Understand the term "diversification":**
- Diversification in biological terms refers to the formation of sub-populations through the accumulation of independent variations. This means that diversification involves changes within a population rather than the emergence of entirely new species.

2. **Evaluate Option A: Mutation**
- Mutation refers to sudden changes in the genetic material, leading to variations. However, mutations are specific events and do not encompass the broader process of diversification, which involves the accumulation of various types of variations over time. Therefore, this option is incorrect.

3. **Evaluate Option B: Mega evolution**
- Mega evolution typically refers to large-scale evolutionary changes that occur over long periods, often leading to the emergence of new taxa. Specific diversification, however, occurs at a smaller scale within a population. Thus, this option is also incorrect.

4. **Evaluate Option C: Micro evolution**
- Micro evolution refers to small-scale evolutionary changes that occur within a population, such as changes in allele frequencies over time. This aligns with the concept of specific diversification, which involves the formation of sub-populations through the accumulation of variations. Therefore, this option is correct.

5. **Evaluate Option D: Macro evolution**
- Macro evolution involves large-scale evolutionary changes that can lead to the emergence of new species or higher taxonomic groups, often influenced by mass extinctions or evolutionary radiations. Since specific diversification refers to changes within a population, this option is incorrect.

### Conclusion:
The correct answer to the question "Specific diversification represents:" is **Option C: Micro evolution**.
