I heard the story about how one monkey on an island figured out how to wash his food, and then other monkeys starting doing it too. That’s the true story of Imo the macaque monkey! In 1952 on the island of Koshima, a primatologist was leaving sweet potatoes on the shore for the monkeys to eat. One smart monkey, a one and a half year old named Imo, began washing the sand off her potatoes in a brook. You can imagine how much better this insight on her part made the potatoes taste! Next, Imo’s playmate was observed washing potatoes. Then her mother, then another peer. In four years, three more of her relatives and four members of another macaque group were washing their food. The primatologist realized he was watching the way new ideas spread in society!
我聽(tīng)到的故事，一個(gè)小島上的猴子想出如何洗他的食物，然后其它的猴子也開(kāi)始洗食物。這是Imo真實(shí)的故事！ 1952年在Koshima小傷傷，一個(gè)靈長(zhǎng)類(lèi)動(dòng)物學(xué)家把一些紅薯放在岸邊讓猴子吃。一只聰明的猴子，一歲半的伊莫，開(kāi)始在小溪中洗去紅薯上的傻子。你能想象如何這回它吃紅薯時(shí)的感覺(jué)更好吃的吃相！接下來(lái)，Imo的玩伴也被觀察到洗土豆。然后，是她的母親，然后是其同輩。在四年中，她的3個(gè)親戚和另一獼猴群落的四名成員也開(kāi)始清洗物。靈長(zhǎng)類(lèi)動(dòng)物學(xué)家意識(shí)到他觀察到的正是新方法在猴群社會(huì)中的傳播方式！
