Question

Darwin's theorized that three conditions were necessary for natural selection to occur, which of the following is NOT one of them?
stable environment
struggle for existence
variation
inheritance

Answer 1

Answer:

The correct option is: stable environment

Explanation:

According to the Darwin's theory, natural selection is the concept by which all the small useful variations of traits are preserved.

According to Darwin, there are three necessary and sufficient conditions for the occurrence of natural selection:

1. struggle for existence

2. variation

3. inheritance

These conditions are said to be necessary because if these conditions are not satisfied then natural selection does not occur.

These conditions are said to be sufficient because if these conditions are satisfied, then natural selection will most definitely occur.
