| To artificial selection we chiefly owe all the many races or varieties of our domesticated animals and plants. |
| One can note that the fur of truly longhaired cats, such as Persians, is, most probably a product of a long artificial selection. |
| Thus, by a simple method of artificial selection, the silkworm industry has been rescued from what threatened to be a collapse. |
| Domestication and artificial selection of livestock have made farm animals dependent on humans. |
| However, genetic differentiations may also be due to artificial selection, since B. davidii was cultivated as an ornamental plant. |
| Initially, the only methods available were artificial selection or hybridization. |
