Question

What is the definition of natural selection?

Answer 1

Natural Selection:

1. Natural selection is the mechanism through which living creature populations adapt and change.
2. It states that the organisms that are able to survive and reproduce with the changing environmental conditions are selected by nature while the ones that cannot survive are eliminated. The genes responsible for the survival of an organism are passed on to the successive generations.
3. Individuals in a population are naturally varied, which means they are all unique in some way.
4. Because of this variety, some people have qualities that are better suited to their environment than others.
5. The change in a population's heritable features over generations is a major evolutionary mechanism.
