A still greater number must be called monstrosities, such as six-fingered men, porcupine men, Ancon sheep, Niata cattle, etc.; and as they are widely different in character from natural species, they throw very little light on our subject.
Ancon sheep (also called "Otter" sheep) are a grouping of domestic sheep with long bodies and very short legs, with the fore-legs being crooked. The term is generally applied to a line of sheep bred from a single affected lamb born in 1791 in Massachusetts, USA. The breed was artificially selected and maintained for its desirable inability to jump over fences. It was allowed to go extinct in 1876 when it was no longer required.
