Differences between Artificial Selection and Natural Selection

Differences between Artificial Selection and Natural Selection

When most people think of evolution, the first thing that comes to mind is natural selection. But what many people don’t know is that there is another important process called artificial selection. This process is used by humans to selectively breed animals and plants for certain traits. While both processes play an important role in evolutionary change, there are some key differences between them. In this post, we will take a closer look at these differences and see which process is more powerful.

What is Artificial Selection?

Artificial selection is the process of selecting individuals with desirable characteristics to breed and produce offspring with those same characteristics. This process can be done by humans, as in the case of choosing to breed dogs with certain physical or behavioral traits, or it can be done by nature, as when only the fittest members of a species survive to reproduce.

Artificial selection can result in significant changes in a population over time, as the genes for desired traits are passed down from generation to generation. In some cases, artificial selection can even lead to the emergence of new species. For example, Darwin’s finches on the Galapagos Islands evolved into different species over time due to different methods of feeding that were favored by each group. Artificial selection is a powerful tool that can be used to change the course of evolution.

What is Natural Selection?

Natural selection is the process by which organisms adapt to their environment. It is one of the main mechanisms of evolution, and it occurs when there is a difference in the survival or reproduction rates of individuals within a population. Natural selection can act on any heritable trait, and it leads to the accumulation of beneficial traits in a population over time.

For example, if a population of animals contains individuals with variations in fur coloration, those with darker fur may be more likely to survive in an environment with predators. As a result, over time, the population will become increasingly composed of dark-furred individuals. Natural selection is a powerful force that can shape entire populations of organisms, and it is responsible for the vast diversity of life on Earth.

Differences between Artificial Selection and Natural Selection

Artificial selection and natural selection are two processes that can lead to changes in a population over time. Artificial selection is the process by which humans select for desired traits in a plant or animal, while natural selection is the process by which these traits arise naturally in a population. Artificial selection can be more direct and controlled than natural selection, but it typically takes longer to produce results. Natural selection is more of a random process, but it can act more quickly than the artificial selection. Artificial selection is usually used to improve domesticated plants and animals, while natural selection typically leads to changes in wild populations.


The differences between artificial selection and natural selection are vast, with implications for both the study of evolution and our understanding of life itself. It is important to understand these concepts if we hope to further our knowledge about how species develop and change over time.
