Fitness is just book-keeping; survival and differential reproduction result from natural selection, which actually is a driving mechanism in evolution. Organisms which are better suited to their environment will reproduce more and so increase the proportion of the population with their traits.

Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature...
Fitness and natural selection were first explained in detail by Charles Darwin, who observed wildlife around the world, took copious notes, then sought to understand what he had seen. Natural selection is probably best explained in his words, taken from his landmark work "On the Origin of Species." Organisms show variation of traits.
Explain how natural selection is related to species' fitness. Over time, natural selection results in changes in the inherited characteristics of a population. These changes increase a species' fitness in its environment. Identify evidence Darwin used to present his case for evolution.
Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected. Identify evidence Darwin used to present his case for evolution.
The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species. Select from these resources to teach your classroom about this subfield of evolutionary biology.
Natural selection is what drives evolution. It's the process in nature by which the organisms best adapted to their environment survive and are better able to transmit their genetic characteristics to the next generation. Natural selection is the process. Evolution is the outcome.
Biologists use the word fitness to describe how good a particular genotype is at leaving offspring in the next generation relative to how good other genotypes are at it. 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.
Natural Selection vs. 'Survival of the Fittest' Natural selection is the idea that species that acquire adaptations favorable for their environment will pass those adaptations to their offspring. Eventually, only individuals with those favorable adaptations will survive, which is how the species changes over time or evolves through speciation.
Charles Darwin was a famous English naturalist. During his life he came up with the theory of natural selection and how this drives evolution of new species. Darwin is associated with the term...
Natural selection promotes the evolution by increasing the gene frequencies of genotypes with greater fitness to the environment. Thereby, organisms with the most suitable phenotypes to the environment are selected to pass the changes to the next generation through reproduction.

Natural selection is a process of adaptation by an organism to the changing environment by bringing selective changes to its genotype or genetic composition. Natural selection is one of the four primary mechanisms of evolution, along with mutation, genetic drift, and migration.
(b) Natural selection states that the organisms which are fit to survive in the existing environment reproduce and increase in number while other die and perish away. Certain changes take place in the organisms which helps it adapt better to a particular environmental condition and these variation are passed to next generation increasing their chances of survival than the others. This theory was given by Charles Darwin and is based on survival of fittest.
