WebbNatural selection leads to changes in allele frequencies in a population, favouring the organisms that are better suited to survive. Natural selection differs from artificial selection as it does not require human intervention. Fitness is an organism’s ability to survive and pass its genes on to future offspring. WebbNatural selection is a mechanism that drives evolutionary change. Simply put, it is the survival of traits that are favorable to an organism within its environment. Think of it in terms of the example above with the mice. You have a popuation of mice with a color variation. Some have genes for tan fur and others have genes for black fur.

WebbThis is also known as ordinary selection because it begins with one individual and it's constitution and habits. Another method of Natural Selection is sexual selection. Sexual selection arises from interspecies cross breeding. This, Darwin explains, deviates from the struggle for existence and becomes the struggle for progeny.

WebbThe concept of fitness is central to natural selection.
