チンパンジーの言語

 
英語学習者として興味を引かれた記事は、チンパンジーがジェスチャーを使って「意味」を伴うコミュニケーションをしているというものです。



残念ながら元の論文The Meanings of Chimpanzee GesturesはSummaryしか読めませんが、BBCが研究者のインタビューやジェスチャーのイラスト入りで丁寧に紹介してくれています。

Chimpanzee language: Communication gestures translated
By Victoria Gill
Science reporter, BBC News

Researchers say they have translated the meaning of gestures that wild chimpanzees use to communicate.

They say wild chimps communicate 19 specific messages to one another with a "lexicon" of 66 gestures.

The scientists discovered this by following and filming communities of chimps in Uganda, and examining more than 5,000 incidents of these meaningful exchanges.

The research is published in the journal Current Biology.



Only humans and chimps, she said, had a system of communication where they deliberately sent a message to another individual.と意図的なコミュニケーションというのは人間とチンパンジーしか見られないようです。Telegraphがどんな意図があるかもう少し詳しく載せていました。

Scientists Translate Chimpanzee and Bonobo Gestures That Resemble Human Language
BY BRANDON KEIM 07.03.14 | 12:22 PM | PERMALINK

One limitation of the researchers’ approach is that it can only identify gestures that provoke an action. Those that convey something more subtle — two chimps talking about the weather, for example, or reminiscing about the good old days — can’t now be interpreted. Whether such conversations occur is an open question.

上の部分で触れていますが、雑談とかをしているわけではなので我々が想像するコミュニケーションとはまだ隔たりがありますよね。
