马赛马拉动物保护区是肯尼亚最受欢迎的旅游胜地,每年有成千上万的动物爱好者观察狮子和豹,或亲眼目睹在坦桑尼亚和肯尼亚之间迁徙的150万头角马。今年动物爱好者们大吃一惊,发现了斑秃的斑马!
英文原文according to a Kenya newspaper,a local tour guide and photographer,was the first to notice the zebra ' s unusual pattern in September
a bio logist at the university of California believes the foal has a genetic condition known as " pseudomelanism "。'
the expert says that specialized skin cells transfer melanin into some of zebras ' hairs .
the parts that obtain the melanin appear black,while those that don't,look white .
On rare occasions,the melanin transfers in a pattern that is different from the familiar stripes .
a similar foal was caught on camera in Botswana in 2014。
experts believe the skin mutations may be more common than we realize .
However,they are rarely seen because most abnormally patterned or colored zebras rarely survive to adulthood .
Their striking looks,which do not blend in with the herd,make them easy targets for hungry lions or hyenas .
中文对照据肯尼亚一家报纸报道,今年9月,当地导游和摄影师首先发现了圆点斑马。加州大学的一位生物学家认为,这匹斑马产生了一种称为“医生黑变病”的基因突变。专家表示,斑马体内有特殊的皮肤细胞,将黑色素转移到斑马的毛色。头发中含有黑色素的是黑色,不含黑色素的部分显示为白色。在罕见的情况下,黑色素转移显示出与普通条纹不同的图案。2014年在博茨瓦纳拍摄了类似的斑马。专家认为皮肤的变异可能比我们通常认为的更普遍。但是,这些花纹或颜色不同的斑马很少活到成年,所以这种变异不容易被发现。与众不同的长相使他们与同伴格格不入,很容易成为狮子或猎犬的狩猎目标。
