Theory of Natural Selection was proposed bya. Charles Darwinb. Hugo de Vriesc. Gregor Johann Mendeld. Jean Baptiste Lamarck

The correct answer is:

a. Charles Darwin

Explanation:

The theory of natural selection was proposed by Charles Darwin in his book "On the Origin of Species," published in 1859. Natural selection is a process by which organisms that are better adapted to their environment tend to survive and produce more offspring. This idea forms a cornerstone of Darwin’s theory of evolution. According to natural selection, variations within a species occur naturally, and those that are advantageous for survival become more common in subsequent generations, leading to evolutionary change over time.

Other options:

b. Hugo de Vries: Hugo de Vries proposed the mutation theory of evolution, which suggests that mutations or sudden changes in the genetic material contribute to evolution.
c. Gregor Johann Mendel: Mendel is known as the father of genetics. He discovered the basic principles of heredity through his experiments with pea plants.
d. Jean Baptiste Lamarck: Lamarck proposed an early theory of evolution based on the idea of inheritance of acquired characteristics, which is not widely accepted today.
Therefore, the theory of natural selection is correctly attributed to Charles Darwin.
