Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	biological evolution
B	asexual reproduction
C	ecological succession
D	gene mutation

Explanation:

Detailed explanation-1: -Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.

Detailed explanation-2: -Darwin called this mechanism natural selection. Natural selection, also known as “survival of the fittest, ” is the more prolific reproduction of individuals with favorable traits that survive environmental change because of those traits.

Detailed explanation-3: -The accumulation of slightly deleterious mutations in populations leads to the buildup of a genetic load and can cause the extinction of populations of small size.

Detailed explanation-4: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
