Artificial selection, also known as selective breeding, has been the most important process in improving the features of plants used as staple foods. For thousands of years, humans have selected and bred plants with desirable traits such as higher yields, better taste, and resistance to pests, leading to the development of the cultivated varieties we rely on today. Genetic engineering, pesticide and herbicide application, and sexual selection have played roles in agriculture, but none have been as influential over human history as artificial selection.
