Hence we can say that natural selection is what natures chooses at its best, while the artificial selection is what humans choose on the kind of its requirements. In the given content we will discuss the differences between natural selection and artificial selection, which could be helpful in knowing them better. Basis for Comparison Natural Selection Artificial Selection Meaning Natural selection involves the natural process of selection, favouring the most fittest which is able to face all types of situations.
Artificial selection involves the artificial process where selection is done by favouring the desired characters in the new organisms. Chances of survival Chances of surviving increased.
Selection of characters is done artificially hence chances of surviving of new breed is at risk whether it is a plant, or animals or any other organism. Process rate Slow and long process.
Controlled by Controlled by nature. Artificial selection is controlled by humans. Performed on Natural selection is performed on all types of organisms. Artificial selection is processed on some selective organisms of humans desires.
Selection of traits Selection is totally based on the adaptable character and the one who is able to cop up in all types of natural conditions.
Selection is done on the basis of required character. Transformation It transforms the entire population of a species. It brings out the new variety of that species. Type of selection Natural selection. Man-made selection. Occurs in It occurs in all kind of natural populations.
It usually occurs in domestic populations. Examples Darwin finches which are group of birds of 14 species of small birds, evolved from the same species of bird on the Galapagos Islands. It is usually performed on pet animals or animals which are used for economical purposes.
The selection of long-necked giraffes by the environment is shown in figure 2. Artificial selection is the selective breeding of animals and plants to produce an offspring with desirable and inheritable characters. Artificial selection is a man-made selection process of desired characters, and it is mainly used in livestock and improved crops. The beneficial characters such as the ability to produce more milk in cattle, the accelerated lean muscle growth, exotic pets such as Savannah cat and small dogs such as Chihuahua are produced by artificial breeding.
A Belgian cow is maintained by selective breeding due to its accelerated lean muscle growth. Furthermore, artificial selection is used in the production of untold diversity in plants. Corn, wheat, and soybeans strains are developed by artificial selection of beneficial traits in agriculture. Broccoli, Brussels sprouts, cabbage, cauliflower, collards, and kale are produced by the careful selective breeding of wild mustard.
Roses and orchids are also cultivated by selective breeding. Artificial selection can also produce various colors in carrot roots.
Figure 4: Carrots with multiple colored roots. Natural Selection: Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. Artificial Selection: Artificial selection refers to the process by which animals and plants are chosen by the breeder to produce desirable and inheritable characters in the successive generations.
Natural Selection: Natural selection is a nature-made selection process. Artificial Selection: Artificial selection is a man-made selection process. Natural Selection: Natural selection produces a huge biological diversity. Artificial Selection: Artificial selection produces organisms with selected traits. Natural Selection: Natural selection occurs in natural populations.
Artificial Selection: Artificial selection mainly occurs in domestic populations. Natural Selection: Natural selection only allows favorable characters to be inherited over the successive generations. Artificial Selection: Artificial selection allows only selected traits to be inherited over successive generations. Natural Selection: Natural selection is a slow process.

In the mids, Charles Darwin famously described variation in the anatomy of finches from the Galapagos Islands. Alfred Russel Wallace noted the similarities and differences between nearby species and those separated by natural boundaries in the Amazon and Indonesia. Independently they came to the same conclusion: over generations, natural selection of inherited traits could give rise to new species.
Use the resources below to teach the theory of evolution in your classroom. Natural selection is the process through which species adapt to their environments.
It is the engine that drives evolution. Charles Darwin and Alfred Wallace developed the idea of evolution through natural selection. But this idea was not accepted by scientists until more evidence came along. Use this infographic to explore how Darwinism and genetics came together to explain what we know today about evolution.
