阅读:关于zebra的stripes保护他们不被predator攻击:
1)stripes会产生visual illusion,让zebras看起来比实际近,让predators在跳跃后抓不到它们
2)黑白条纹让predators很难一群中定位目标单个的斑马
3)stripes会让zebras blend into environment,,是种保护色
听力一一反驳:
1)predators如lions一般不leap,一般在平原上追赶.
2)科学研究证明stripes的图案和solid colors对lions一样,不会confused,不会犹豫
3)zebras从不hid themselves而是喜欢在开放性的空间,而且它们是相对noisy的动物,在开放空间遇到危险时更容易逃走
