我们平常注意到,猴子的眼睛又黑又亮,没有眼白,黑猩猩的眼睛也是如此。那么,为何它们的眼睛没有眼白呢?其实,在灵长类动物中,除了人类的眼睛黑白分明外,其他动物的眼睛都和猴子、黑猩猩的一样,我们看不到它们的眼白部分。当然,它们并非没有眼白,只是眼白呈茶褐色,很难与眼黑区 We usually notice that the monkey’s eyes are dark and bright, no white eyes, and the eyes of chimpanzees are the same. So, why aren’t their eyes white? In fact, in primates, except for human eyes, which are black and white, the eyes of other animals are the same as those of monkeys and chimpanzees. We cannot see the white parts of them. Of course, they are not white, but their eyes are dark brown, and it is difficult to see dark areas.
