An evolutionary trend in which there is general degeneration and loss of organs is

Options

A. Progressive
B. Vestigial
C. Retrogressive
D. Stasigenesis

Answer

To solve the question regarding the evolutionary trend characterized by the general degeneration and loss of organs, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Evolutionary Trends**:
- Evolutionary trends refer to the patterns of change in organisms over time, which can include the development of new traits or the loss of existing ones.

2. **Identify the Key Terms**:
- The question specifically mentions "general degeneration and loss of organs." This indicates a trend where complexity decreases over time.

3. **Analyze the Options Provided**:
- **Progressive**: This refers to an increase in complexity and the development of advanced characteristics. This does not match our requirement.
- **Vestigial**: This term refers to organs that are present but non-functional. While it involves loss, it doesn't necessarily imply a trend of degeneration.
- **Retrogressive**: This describes a trend where there is a reduction in complexity and a loss of advanced characteristics, aligning closely with the concept of degeneration.
- **Stasigenesis**: This refers to a lack of change over time, which does not relate to degeneration or loss of organs.

4. **Select the Correct Answer**:
- Based on the analysis, the option that best describes an evolutionary trend involving degeneration and loss of organs is **retrogressive**. This option indicates a decrease in complexity and the forsaking of advanced structures.

5. **Conclusion**:
- Therefore, the correct answer to the question is **Option 3: Retrogressive**.
