Even some of our smaller primate cousins like this tarsier.

甚至还有一些比我们体型更小的灵长类近亲，如这只眼镜猴。

A baby tarsier shows off its huge peepers, which are larger than its brain.

一只眼镜猴宝宝炫耀着它巨大的眼睛，比它的大脑还大。

Human beings are part of the primate family of animals, which include all kinds of apes, monkeys, tarsiers, lemurs, and lorises.

人类是灵长类动物家族的一部分，包括各种猿类、猴子、眼镜猴、狐猴和懒猴。

Why don't we have monkeys and tarsiers and lemurs wandering around the U.S. and Canada today?

为什么我们今天没有在美国和加拿大四处游荡的猴子、眼镜猴和狐猴？

The tarsier's enlarged orbs haven't evolved to make it cuter, however, but to gather as much light as possible.

然而， 眼镜猴扩大的眼球并没有进化成更可爱的样子，而是为了尽可能多地收集光线。

While tarsiers scan the nocturnal scene with their enormous peepers, cats use gleaming eyes to do the same.

眼镜猴用它们巨大的窥视器扫视夜间的场景，而猫用闪闪发光的眼睛做同样的事情。

Take the tarsier, whose eyeballs are each as big as its brain, giving it the biggest eyes compared to head size of all mammals.

以眼镜猴为例， 它的每个眼球都和它的大脑一样大，因此与所有哺乳动物的头部大小相比， 它的眼睛最大。

These traits, along with a few others, define the taxonomic order of Primates, which includes humans, apes, monkeys, tarsiers, lemurs, and bushbabies, to name just a few.

这些特征以及其他一些特征定义了灵长类动物的分类顺序，其中包括人类、类人猿、猴子、眼镜猴、狐猴和丛林宝宝等等。

In this, too, it resembles agile (and even more wide-eyed) tarsiers, which are the only existing primates to enjoy an exclusively carnivorous diet of bugs, as well as small birds, snakes, lizards and bats.

以上特征说明它和敏捷的眼镜猴（这种动物的眼眶更大）相似，现存的灵长类动物中，只有眼镜猴喜欢吃虫子、小鸟、蛇、蜥蜴和蝙蝠。

As they report in Nature, the critter, which lived around 55m years ago, in the Eocene epoch, seems to be the most primitive relative of tarsiers, mouse-sized primates which now inhabit the islands of South-East Asia.

这种生活在大约五千五百万年前始新世时期的动物似乎是眼镜猴（这种灵长类动物有老鼠一样的体型，现在居住在东南亚的岛屿上）最原始的亲戚。
