Life is distributed all over cosmos in the form of resistant spores as per this concept

Options

A. Theory of Abiogenesis
B. Theory of Biogenesis
C. Theory of Catastrophism
D. Theory of Panspermia

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question states that life is distributed all over the cosmos in the form of resistant spores. We need to identify the correct concept that supports this idea.

2. **Analyzing the Options**:
- **Theory of Abiogenesis**: This theory suggests that life originated from non-living matter on Earth. It does not support the idea of life being distributed in the cosmos, so this option is incorrect.

- **Theory of Biogenesis**: This theory states that life arises from pre-existing life. It implies that life cannot originate from non-living matter, which does not align with the concept of life being distributed in the cosmos. Thus, this option is also incorrect.

- **Theory of Catastrophism**: This theory posits that the Earth has been shaped by a series of sudden, short-lived, and violent events. It does not relate to the distribution of life in the cosmos, making this option incorrect as well.

- **Theory of Panspermia**: This theory suggests that life exists throughout the universe and is distributed by meteoroids, asteroids, comets, and planetoids. It specifically states that life may have come to Earth from other planets in the form of spores or seeds. This aligns perfectly with the concept presented in the question.

3. **Conclusion**: Based on the analysis of the options, the correct answer is the **theory of panspermia**. This theory supports the idea that life is distributed across the cosmos in the form of resistant spores.
