Which statement accurately describes the difference between artificial and natural systems of classification?
| 1. | Artificial systems utilize genetic similarities, whereas natural systems use morphological characteristics. |
| 2. | Artificial systems classify organisms based on a few characteristics, while natural systems consider a large number of characteristics. |
