Question

Who proposed the theory of organic evolution by natural selection?

• A. Charles Darwin
• B. Lamarck
• C. Gregor Johann Mendel
• D. Hugo de Vries

Hint:

Charles Darwin is credited with developing the theory of natural selection, which explains how species evolve over time.

Answer 1

The Correct Option is A

The theory of organic evolution by natural selection was proposed by Charles Darwin. According to this theory, organisms with traits that are advantageous for survival in a particular environment are more likely to reproduce and pass those traits to their offspring. Over time, these advantageous traits become more common in the population.
Step 1: Charles Darwin.
Charles Darwin is renowned for his groundbreaking work on the theory of natural selection, which he proposed in his book, On the Origin of Species (1859). This theory revolutionized the understanding of how species evolve over time.
Step 2: Lamarck.
Lamarck proposed the theory of inheritance of acquired characteristics, which stated that traits acquired during an organism’s lifetime could be passed to offspring. This theory is now largely discredited in favor of Darwin’s natural selection theory.
Step 3: Gregor Johann Mendel.
Mendel is known for his work on genetics and the laws of inheritance, but he did not propose a theory of evolution. His work laid the foundation for modern genetics but did not address the process of natural selection.
Step 4: Hugo de Vries.
Hugo de Vries is known for his work on mutation theory and for rediscovering Mendel’s laws of inheritance, but he did not propose the theory of natural selection.
Step 5: Conclusion.
Therefore, the correct answer is (A) Charles Darwin, who proposed the theory of organic evolution by natural selection.
