Question

The major idea portrayed in Darwin's book "The origin of species" was that

• A. All organisms live in social colonies
• B. Continuous variation has no relationship with environmental changes
• C. Disproved Lamarck's theory
• D. Species change over time depending on natural conditions

Answer 1

The correct option is D

Species change over time depending on natural conditions

Darwin's main idea portrayed in his book "The origin of species" is that all species change over time depending on environmental factors.

These changes help them survive in their environment and those organisms that do not show any variation to suit the environment, perish. This observation led to the theory of "Natural selection".
