Question

What are the four principles of natural selection?

Answer 1

Natural Selection:

It is the process by which living organisms adapt and change according to the surroundings around them. The different adaptations lead them to develop variations that make them better suited for the environment.

The four principles of natural selection are:

1. Heredity: Heredity, also known as inheritance or biological inheritance, is the transfer of qualities from parents to their offspring. Cells or creatures born from asexual or sexual reproduction inherit the genes of their parents.
2. Variations: Genetic variation is the variance in DNA between people or communities. Two of the many sources of genetic diversity are mutation and genetic recombination.
3. Survival of the fittest: The term "survival of the fittest" was first used to describe the process of natural selection in Darwinian evolutionary theory. The biological idea of fitness is defined as reproductive success.
4. Struggle for existence: The term "struggle for existence" refers to the struggle for the resources needed to survive. It can be used to describe either natural or human societies.
