How did zebras get their stripes? It's hard to get a black-and-white answer. 斑马身上的条纹是如何形成的？我们很难得到确切的答案。 Some scientists say the stripes are a form of camouflage that protects zebras from hungry lions. Others say they're key to zebra mating rituals. Just last year, researchers published research suggesting that the stripes repel biting flies, thus protecting the animals from diseases flies sometimes carry. 有些科学家认为，条纹是一种伪装的形式，保护斑马免落狮口。另一些科学家则认为，条纹在斑马的求偶仪式中起到关键作用。2017年，有研究人员发表研究称，条纹能够赶走苍蝇，保护斑马远离苍蝇经常传播的疾病。 But a peculiar new study offers yet another possible explanation: the stripes help the zebras stay cool in their sometimes sweltering habitats. 一项特殊新研究提供了另一种可能的解释：斑马的栖息地有时会变得闷热难耐，条纹能助它们保持凉爽。 |
