The domestication or breeding of animals to have as pets, livestock on farms, or for work purposes is a form of artificial selection. Charles Darwin used these practices to support his theory of species change by natural selection. How is artificial selection similar to natural selection?   When animals with favorable traits are bred with animals with unfavorable traits, the offspring will have favorable traits, so breeders were changing species by removing certain traits.   For artificial selection to work, only the strong survive to reproduce.   By breeding animals with specific traits, breeders were able to produce a wide variety of breeds within a short peri

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
