LIFE SCIENCE

Detailed explanation-1: -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-2: -Darwin coined the term fitness to refer to an organism’s relative ability to survive and produce fertile offspring.

Detailed explanation-3: -Darwinian fitness describes how successful an organism has been at passing on its genes. The more likely that an individual is able to survive and live longer to reproduce, the higher is the fitness of that individual.

Detailed explanation-4: -This means that if an environment changes, the traits that enhance survival in that environment will also gradually change, or evolve. Natural selection was such a powerful idea in explaining the evolution of life that it became established as a scientific theory.

Detailed explanation-5: -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.
