Definition of Natural selection:
In modern biology, natural selection is a process whereby species which have traits that enable them to adapt in an environment survive and reproduce, and then pass on their genes to the next generation. Natural selection means that species that can adapt to a specific environment will grow in numbers and eventually greatly outnumber those species that cannot adapt.
The natural selection process enables a species to better adapt to its environment by changing its genetic configuration with every new generation. These changes are gradual and may occur over thousands of years, although in some instances natural selection may occur much faster, especially in species with short life spans and rapid reproduction rates.
Process by which evolutionary changes occur in living organisms over millions of years. According to Darwins theory of evolution, the organisms well adapted to their environment survive better than those who are not and are able to pass on their genes to many more offspring. As this process repeats over hundreds of thousands of years and the less-fit organisms become extinct, it appears as if nature selects certain organisms over others in the same environment to continue. This biological concept is used as a metaphor for modern economic environments where very rapid pace of change requires agility in adjusting to the unanticipated situations or to lose out. Also called survival of the fittest it is, however, not the main feature of evolution. The main evolutionary feature is the continuation of what works well (see evolution).
