According to scientists, adult monkeys can recognize photographs of their friends, the BBC reported.

In an experiment, untrained Barbary macaques showed interest in photos of other monkeys but spent more time scrutinizing pictures of unfamiliar animals. Juvenile monkeys were fascinated, but puzzled by the photographs and often tried to greet or touch the animal in the image.

The findings suggest that primates learn over time to understand that photos are representations of faces. As well as adding to our knowledge of their intelligence, the findings, published in the journal Animal Cognition, could help in future studies of primate behavior. （點擊英國廣播公司網站查看原文）

猴子能從照片認朋友

?????? 據英國廣播公司報道，科學家發現，成年猴子可以從照片中認出自己的同伴。

?????? 實驗中，未經訓練的巴巴利獼猴對照片頗有興趣，而且花更多時間審視其不熟悉的動物照片。而未成年的猴子盡管被照片所吸引，但表情困惑，試圖與其中的動物打招呼或者觸摸它們。

?????? 研究結果顯示，靈長類動物隨著年齡增長能意識到照片是面孔的縮影。這項發表在《動物認知》雜志上的成果，不但豐富了我們對猴子智力的認知，而且對未來靈長類動物行為研究也有很大幫助。
