The natural selection process enables a species to better adapt to its environment by changing its genetic configuration with every new generation. Browse natural selection explanation with biology terms to study for online university degree programs. Contrasting the differences between size-selective fishing and balanced harvesting in order to ensure an adequate fish supply for future generations. The limited resources available in an environment promotes competition in which organisms of the same or different species struggle to survive. While the ability to adapt to recent changes in the industry may be a good indicator of a company's or trader's overall aptitude, it does not guarantee that they will be able to adapt to all future changes in the business environment.

It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Accessed Sept. 9, 2020. The choosing of breeding stock on the basis of ancestral reproductive ability and quality is known as pedigree selection. Selection, in biology, the preferential survival and reproduction or preferential elimination of individuals with certain genotypes (genetic compositions), by means of natural or artificial controlling factors. So, no organism is perfectly adapted to its environment. These qualities are economically or aesthetically desirable to humans, rather than useful to the organism in its natural environment. The theory of evolution by natural selection was proposed by Charles Darwin and Alfred Russel Wallace in 1858. Natural selection is a pressure that causes groups of organisms to change over time.
