Coverstone of theory of Darwin was:

Options

A. natural selection
B. inheritance of acquired characters
C. omnis cellulae e cellulae
D. higher productivity

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks for the cornerstone of Darwin's theory. This implies we need to identify the fundamental concept that underpins Darwin's ideas about evolution.

2. **Evaluate the Options**:
- **Option 1: Natural Selection**: This is a process where organisms better adapted to their environment tend to survive and produce more offspring. This concept is central to Darwin's theory of evolution.
- **Option 2: Inheritance of the Acquired Characters**: This idea, proposed by Lamarck, suggests that traits acquired during an organism's lifetime can be passed on to offspring. This is not a cornerstone of Darwin's theory.
- **Option 3: Omnis cellula e cellula**: This phrase means "all cells come from cells," which is a principle of cell theory established by Virchow, not related to Darwin's theory of evolution.
- **Option 4: Higher Productivity**: This concept does not specifically relate to Darwin's theory and is not a recognized principle within it.

3. **Identify the Correct Answer**: After evaluating the options, it is clear that the cornerstone of Darwin's theory is **Natural Selection**. This concept explains how species evolve over time through the survival and reproduction of individuals with favorable traits.

4. **Conclusion**: The correct answer to the question is **Natural Selection**.
