This ancestor looks more like today's Old World monkeys, but still a primate.

这个祖先看起来像东半球的猴子，但还是灵长目。

In the early 1960s, Colin Groves of the Australian National University began a systematic survey of the 250-plus known species of primate.

20世纪60年代初，澳大利亚国立大学的科林·格罗夫斯开始系统研究250多种已知的灵长目。

Of mammals only humans and some primates enjoy color vision. The red flag is black to the bull. Horses live in a monochrome world .

在哺乳中，只有人和一些灵长目能够分辨颜色。红旗在公牛看来是黑色的，马则生活在一个单色的世界里。

Very funny.? Neil is referring to the fact that all humans are descended from apes, and apes and monkeys belong to a group of animals called primates.

很好笑。尼尔是在说人的祖先是猿这个事实，而猿和猴子同属于一，被称为灵长目。

" And it suggests that we see illusory faces because, like other social primates, our brains are so tuned into faces, we don't want to miss a single face in the environment, even if that means occasionally making a mistake."

“这说明，像其它好社交的灵长目一样，我们能看到虚拟面孔是因为大脑如此了解面孔，我们不想错过环境中的面孔，哪怕偶尔会误认。”
