The theory of natural selection was given by

Options

A. Lamarck
B. Alfred Wallce
C. Charles Darwin
D. Oparin and Haldane.

Answer

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

1. **Identify the Theory**: The question asks about the theory of natural selection, which is a fundamental concept in the study of evolution.

2. **Link to Evolution**: Natural selection is closely related to the process of evolution, explaining how species change over time due to variations in traits.

3. **Recognize the Scientist**: The theory of natural selection was proposed by a prominent figure in biology, specifically a British naturalist.

4. **Name the Scientist**: The scientist who formulated the theory of natural selection is Charles Darwin.

5. **Explain the Concept**: Darwin's theory suggests that within any population, individuals exhibit variations. Some of these variations are beneficial, enhancing the organism's chances of survival and reproduction.

6. **Define Key Terms**: The term "fitness" in this context refers to the ability of an organism to survive and reproduce in its environment. Organisms with advantageous traits are more likely to survive and pass those traits to their offspring.

7. **Summarize the Mechanism**: Over generations, beneficial traits become more common in the population due to the survival and reproduction of those individuals that possess them. This leads to the evolution of new species.

8. **Conclude**: Therefore, the theory of natural selection, which explains how evolutionary changes occur through the survival of the fittest, was introduced by Charles Darwin.

**Final Answer**: The theory of natural selection was given by Charles Darwin.
