物种起源 So it has probably been with the turnspit dog; and this is known to have been the case with the ancon sheep. 所以它可能与 turnspit 狗有关； 众所周知， 安康羊就是这种情况。 物种起源 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. 还有更多的人必须被称为怪物， 例如六指人、豪猪人、安康羊、尼亚塔牛等；由于它们在性质上与自然物种有很大不同， 因此它们对我们的主题几乎没有任何启发。

安康羊安康羊（英语：Ancon sheep，又名英语："Otter" sheep）是一种家羊，有着长躯体和极短的短腿，且前腿是弯曲的。该术语通常用于指代由生于1791年马萨诸塞州的一只羊所繁育的后代。该品种由人工选择而成，并维持其无法跳越围栏的性状，但当不再需要时，于1876年灭绝。 “安康”的名称也用于指其他具有相同表现型品系的绵羊，例如从生于1919年的个体繁育的挪威原种，和从生于1962年的个体繁育的德州原种。在科学家不再需要他们的基因用作研究后，也让这些谱系灭绝。 英国莱斯特的考古发掘还发现，约公元1500年出现了有安康羊特征的掌骨、跖骨、趾骨，从而表明该表现型至少已独立出现过四次。

Ancon sheep 安康羊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. |
