Functionality. The trait must have a function. Traits must do something for natural selection to take place. Advantage. To be selected for passing on to descendants, the trait must confer an advantage on the organism that has it, or make the organism more fit for survival in its environment. Origin.
The first of these factors that must be present in order for Natural Selection to occur is the ability of a population to overproduce offspring.

Beagle during the 1830s gave him the opportunity to see evidence of natural selection, although he didn't realize it at the time.The core of Darwin's theory is natural selection, a process that occurs over successive generations and is defined as the differential reproduction of genotypes. Natural selection requires heritable variation in a given trait, and differential survival and reproduction associated with possession of that trait.
Charles Darwin published his scientific theory of natural selection in a book called ‘On the Origin of Species’ in 1859.In On the Origin of Species (1859), Darwin explained: “if variations useful to any organic being do occur, assuredly individuals thus characterised will have the best chance of being preserved in the struggle for life; and from the strong principles of inheritance, will then tend to produce offspring similarly characterised” (p127).Charles Darwin was a naturalist of the 1800s who became the foremost name in the theory of evolution. He promoted the idea of “survival of the fittest” that embraced the theory of natural selection.Individuals in a population that differ from one another. Heritability.

Key principles of genetics were developed from Mendel’s studies on peas. 1. Fundamental theory of heredity.
