The whales appear to prefer the company of "like-minded" individuals, based on common vocal clicking behavior—an example of culture, researchers say. Christopher Intagliata reports

研究人员表明鲸好像更乐意跟有着类似轻唱行为的同类共处鲸群中的一种文明。

We humans are social creatures—we stick together. Family traditionally came first. Then more distant relatives. Then larger groups of unrelated individuals, connected by culture. But it turns out the same could be said for . "So usually you find the female, and their mom and the grandmas and their aunts, ."

咱们人类是社会性生物——咱们互相扶持、团结一致。传统观念中,家庭才是第一位的,排在家庭之后的是间隔稍远的亲属,大批靠文明联络的没有亲缘联络的人就要再靠后站了。对抹香鲸来说,这样的亲疏联络相同适用。“所以你常常会发现雌性抹香鲸会和它们的母亲、外婆以及七大姑八大姨共同生活好多年。

Maurício Cantor, a biologist at Dalhousie University in Halifax, Nova Scotia. He says those closely related family groups then seek out other families with similar behavior: "They tend to hang out or stay together with those who produce the same kinds of sounds." <<whale clicking sound>> Meaning whale cliques are based on producing similar clicks.

戴尔豪斯大学的生物学家毛利西· 康托(Maurício Cantor)说,那些联络亲近的家庭群领会寻觅行为类似的其他家庭集体“抹香鲸们喜爱跟声响类似的同类一同游玩或共处。”这意味着鲸的圈子是靠类似发声维系的。

And similarly clicking whales don't just hang out together, he says. They also emulate each other's songs, or codas. Meaning clans of whales evolve their own dialects—their own form of culture. And these dialects are key. Cantor and colleagues built a computer simulation of generation after generation of virtual whales. And they found that no other factor—like genetics or mother-daughter teaching—could explain the emergence of the clans and dialects in real sperm whale society. The study appears in the journal Nature Communications. [Mauricio Cantor et al, ]

康托还表明,发声类似的鲸不仅仅会一同游戏,它们还会仿照互相的歌声或尾音。 也就意味着鲸的氏族会发展出它们独有的方言——它们独有的文明方式。这些方言非常要害。Cantor和它的搭档计算机模拟了虚拟鲸代代繁殖 。他们没有发现其他要素比方基因或家长教育能够解说鲸类氏族的来源以及实在抹香鲸社会中的方言。研究成果宣布在《天然·通讯》Nature Communications上。[Mauricio Cantor et al, ]

"I'm not trying to say that the types of culture the whale has are the same as human culture. Obviously human culture is much more diverse and complex and cumulative and symbolic. But it's very fascinating just to see that they can have some type of similarities, they can have their own type of culture." And maybe a better understanding of that whale culture, he says, might persuade a few human cultures to be a bit more conservation-minded, when it comes to whales.

“我并不是要企图阐明鲸的文明和人类的文明相同。很显然,人类的文明更为复杂多变,更具累积性与象征性。可是发现抹香鲸与咱们的某种类似性,发现抹香鲸也具有自己的文明,这是一件令人奇的事 康托说。他还以为,更好地了解鲸的文明可能会压服处于某些文明 下的人能用维护的眼光看待鲸。
