Since this is an odd number, it cannot be evenly divided into chromosome pairs, which makes natural reproduction almost impossible.<\/p>\n\n\n\n
In the Bible, it is probably mules \u2013 or \u00abmulis\u00bb \u2013 that are mentioned, not hinnies, although linguistically the two variants may not have been distinguished at all. As far as can be reconstructed historically, hinnies played hardly any role compared to mules. Even today, of the 14 million \u00abmules and hinnies\u00bb worldwide, only about two million are hinnies, while twelve million are mules. The Hebrew word pered<\/em> (13\u00d7) probably denotes the mule in general and the male mule in particular, whereas the feminine form pirda<\/em> (1Kgs 1:33.38.44) refers to the female mule. As a unit of measure, the special expression \u00abmassa zemed peredim<\/em>\u00bb \u2013 \u00abthe load of a pair of mules\u00bb \u2013 also occurs (2Kgs 5:17). Since the breeding of mules was forbidden to the people of Israel by the commandment \u00abYou shall not let your livestock breed with a different kind\u00bb (Lev 19:19), they were probably imported predominantly from other countries (for example Armenia: Ezek 27:14).<\/p>\n\n\n\n Because the results of this crossbreeding look very different depending on the horse and donkey breeds involved, no general distinguishing feature between mule and hinny can be named. If the parent animals belong to the same breed and both variants can be compared directly, both resemble their mother more closely. That is to say: a hinny looks more like a donkey, and a mule more like a horse. This also applies to social behavior, since the animals grow up with their mother (and usually also with other mares and foals). Before cytogenetic examinations in the laboratory were possible, this was the only reliable proof: the animal was placed between a herd of horses and a herd of donkeys \u2013 the mule immediately joined the horses, and the hinny joined the donkeys.<\/p>\n\n\n\n The \u00abproduction\u00bb of these hybrids is no simple undertaking, since the animals must be accustomed to one another and, moreover, in many cases premature termination of pregnancy occurs. In hinnies, the abortion rate is over 80%. This is the main reason why this variant was hardly bred. In mules, by contrast, it is \u00abonly\u00bb about 20%. The males of both hinnies and mules are fundamentally infertile, and in females pregnancies occur only in rare exceptional cases when they are \u00abcovered\u00bb by horse or donkey stallions.<\/p>\n\n\n\n Why should one go to so much trouble to breed an animal that is neither horse nor donkey and cannot even reproduce? The answer is simple: because a mule combines the best characteristics of both species. On the one hand, it is docile and obedient like a horse, somewhat slower and smaller, but almost just as strong.<\/p>\n\n\n\n On the other hand, it is as robust, sure-footed, free from vertigo, weather-resistant, enduring, fearless, prudent, long-lived (they often live to be over 50 years old!), and undemanding as a donkey. Where they are still used today (military, disaster relief), they carry a payload of 150\u2013200 kilograms over 40\u201350 kilometers per day. Since in both donkeys and horses pregnant females were hardly usable for work anyway, and males only became useful after castration (which was forbidden in Judaism), the infertility of mules was not a major disadvantage.<\/p>\n\n\n\n In antiquity, mules enjoyed an excellent reputation and were considered just as noble as horses. In the Roman Empire, where legionaries on foot as perfected infantry bore the main burden of combat, while mounted warriors of the cavalry played only a subordinate role, but where very many transport tasks for the military, trade, and construction projects had to be managed, mules were even clearly preferred. The veterinarians of the legions insisted on being titled not horse doctors (equomedici<\/em>), but mule doctors (mulomedici<\/em>).<\/p>\n\n\n\n A battle-hardened warrior like David probably deliberately chose a female mule as his royal mount (1Kgs 1:33.38.44), since horses were less suitable in the Judean hill country. His sons also rode mules (2Sam 13:29), and this proved fatal for Absalom when his mount ran on while he became caught by his hair in the branches of a tree and hung there until he was found and killed (2Sam 18:9).<\/p>\n\n\n\n In various military conflicts, the limitations of horses, which are not as sure-footed and free from vertigo, played a role \u2013 not only because one could not take chariots into mountainous terrain (Jos 17:16; Judg 1:19), but also because horses could only exploit their strengths on level ground (1Kgs 20:25; Am 6:12).<\/p>\n\n\n\n Sources<\/strong>:<\/strong><\/p>\n\n\n\n<\/a><\/a><\/a><\/a><\/a><\/a><\/figure>\n\n\n\n
