One can note that the fur of truly longhaired cats, such as Persians, is, most probably a product of a long artificial selection. |
Initially, the only methods available were artificial selection or hybridization. |
Perhaps a study of the artificial selection of livestock would provide a clue. |
Following on from The Blind Watchmaker it deploys computer models of artificial selection. |
