One family generally dines on Chinese takeout while their neighbors eat home-cooked meatloaf. You say potato, I say potahto. And humans aren’t the only primate species with cultural differences: even in the same environment, different groups of chimpanzees use different tools. The work is in Current Biology.
有一家人经常在中国快餐店吃饭，而他们的邻居则吃的是烘肉卷。土豆的读法因人而异，人类并不是唯一出现这样拥有不同选择的灵长类动物，就在同样的环境下，不同的黑猩猩使用不同的工具作业。这是当代生物学研究的课题。
Chimps living in a national park in Cote d’Ivoire like eating Coula nuts. They hammer them open with stone or wood. At the beginning of the season, the nutshells are harder. So you might expect all the chimps in the forest to initially use stone hammers and then switch to easy-to-find wooden tools when the nut-cracking requires less force.
生活在科特迪瓦国家公园的黑猩猩喜欢吃考拉果。他们用石头或者木棍砸开考拉果，在每个季节的初期，这种果壳就会变得非常坚硬。你可以想象所有的黑猩猩们最先开始选择用石头捶开果壳，到后来不再需要大力气剥开时，就会使用木棍，很显然木棍到处都有。
But researchers examined the tool use of three different chimpanzee communities—and found that despite sharing genes and a habitat, each group chose their hammers differently.
研究人员检查3个不同黑猩猩群体使用的工具情况，发现尽管有着相同的基因和栖息地，但是他们使用的工具却不同。
For example, one group preferred stone hammers throughout the Coula nut season. Another gradually transitioned from primarily stone to primarily wooden tools. And the third community switched from stone to wood more quickly. Hammer size also varied from group to group.
例如，有一群黑猩猩喜欢一直使用石锤砸开考拉果，还有一群则喜欢开始主要用石锤，到后来慢慢地过渡到主要用木棍。第3组黑猩猩则会迅速地从石锤转变到木棍。这种工具的大小也会因为群体的不同而不同。
As a chimp might explain, you say tomato, I say [chimpanzee calls].
黑猩猩也许会解释说，你说你的西红柿，我说我的“猩猩语”。
