Evolutionary biologists use the word fitness to describe how good a particular genotype is at leaving offspring in the next generation relative to other genotypes. So if brown beetles consistently leave more offspring than green beetles because of their color, you'd say that the brown beetles had a higher fitness. In evolution, fitness is about success atEvolution - Natural Selection, Adaptation, Genetics: The central argument of Darwin’s theory of evolution starts with the existence of hereditary variation.

Abstract. In his qualitative theory of natural selection, Darwin (1859) proved that selection is able to produce adaptive heritable changes in populations. His qualitative reasoning, however, did not satisfy the founders of theoretical population genetics. Their major task was to establish a quantitative theory which could derive the rates of ...What are the 4 components of natural selection? Overproduction - more offspring is produced that survives.

Natural selection, Darwin argued, was an inevitable outcome of three principles that operated in nature. First, most characteristics of organisms are inherited, or passed from parent to offspring, although how traits were inherited was unknown. Second, more offspring are produced than are able to survive.
