Selective breeding
|
Detailed explanation-1: -Artificial selection, also called “selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.
Detailed explanation-2: -Selective breeding of domesticated animals shows that artificial selection can cause evolution. Evolution of homologous structures by adaptive radiation explains similarities in structure when there are differences in function. Populations of a species can gradually diverge into separate species by evolution.
Detailed explanation-3: -Because of selective breeding, future generations of selectively bred plants and animals will all share very similar genes which will reduce variation.
