The most aggressive apes of all were the bonobos .

所有的猿类中最具攻击性的是倭黑猩猩。

In the wild, bonobos are known to beat on hollow trees.

在野外，倭黑猩猩以能在中空的树上击打出节奏而闻名。

But researchers have found that both sea lions and bonobos are also capable of bopping to abeat.

但是，研究人员发现，海狮和倭黑猩猩也有乐感。

Now, given that bonobos are closely related to humans, their rhythmic ability might not soundvery surprising.

由于倭黑猩猩是人类的“近亲”，它们具有节奏感也许并不稀奇。

There are primates like bonobos who copulate for 15 seconds at a time, and yet they still have a baculum.

有些像倭黑猩猩这样的灵长类动物，一次交配仅需15秒，但它们仍然具有阴茎骨。

And a study in the journal Current Biology suggests that their laid-back development keeps bonobos forever young.

《当代生物学》杂志中的一项研究表明宽松的成长环境让倭黑猩猩拥有一颗童心。

Kivell and Schmitt suggested these features may be absent in gorillas as they knuckle-walk in a fundamentally different way from chimps and bonobos.

凯威尔和施密特指出，由于行走方式与黑猩猩和倭黑猩猩有着根本的不同，大猩猩缺少这些特征。

Researchers beat a drum at around 280 beats per minute and found that bonobos wereable to pick up the beat and play it on a specially designed drum.

研究人员以每分钟约280次的速度击鼓，发现倭黑猩猩能够跟上节奏，并在一个特制的鼓上演奏出来。

These adaptations -- long legs and arches in our feet -- represent major differences between us and our distant primate relatives including gorillas, chimps and bonobos.

这些适应性特征，即大步伐走路和弓形脚底，正是现代人类以及与我们有遥远亲缘关系的大猩猩、黑猩猩、倭黑猩猩等类人猿之间的重要区别。

Bonobos on the other hand are famously playful and friendly.

巴诺布猿以其顽皮和友好而著称。
