What is the difference of artificial selection and genetic engineering?

Artificial selection is the process by which humans breed plants or animals for specific traits over generations, relying on natural reproductive methods to enhance desired characteristics. In contrast, genetic engineering involves directly manipulating an organism's DNA using biotechnological techniques to introduce, remove, or alter genes, allowing for precise modifications that may not occur through traditional breeding. While both methods aim to improve organisms for human use, artificial selection relies on existing genetic variation, whereas genetic engineering creates new genetic combinations.
