Options

A. We learn that life cannot exist anywhere else
B. We learn about the unity and diversity of living organisms
C. We learn that human species has the responsibility to conserve nature.
D. Human species is the most evolved, so , no harm can come to us

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Importance of Studying Origin and Evolution:**
- The study of the origin and evolution of life is crucial because it helps us understand the history of life on Earth. This includes the development of various species over time and how they have adapted to their environments.

2. **Learning about Flora and Fauna:**
- By studying the evolution of life, we gain insights into the flora (plants) and fauna (animals) that existed during different geological periods. This knowledge helps us understand the ecological dynamics of past environments.

3. **Exploring Species Diversity:**
- The study of evolution allows us to explore the diversity of species. We can learn how different species are related, their adaptations, and how they have evolved in response to environmental changes.

4. **Unity and Diversity of Living Organisms:**
- One of the key benefits of studying evolution is that it reveals the unity and diversity of living organisms. While species may appear different, they often share common ancestors, highlighting the interconnectedness of life.

5. **Evaluating the Options:**
- The question provides several options regarding the usefulness of studying the origin and evolution of life.
- Option 1 suggests that we learn that life cannot exist anywhere else, which is incorrect as the study of evolution does not limit the existence of life to Earth.
- Option 2 states that we learn about the unity and diversity of living organisms, which is accurate and reflects the main benefit of studying evolution.

6. **Conclusion:**
- After evaluating the options, the most appropriate answer is that studying the origin and evolution of life helps us learn about the unity and diversity of living organisms.

**Final Answer:**
- It is useful to study the origin and evolution of life because we learn about the unity and diversity of living organisms.
