ANATOMY

Detailed explanation-1: -Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Detailed explanation-2: -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. This leads to evolutionary change, the trait becoming predominant within a population.

Detailed explanation-3: -Mutations are the source of new variation. Natural selection itself does not create new traits; it only changes the proportion of variation that is already present in the population.

Detailed explanation-4: -It’s called ‘natural selection’ because it’s a way of selecting organisms with certain traits that’s driven completely by nature, compared to ‘artificial selection’ such as when humans breed sheep to become more wooly and more tame by deliberately cross-breeding and selecting for desirable-to-humans traits.

Detailed explanation-5: -Evolution is defined as the change in the inherited traits of a population of organisms through successive generations. When living organisms reproduce, they pass on to their progeny a collection of traits.
