你相信除了人類以外,還有其他動物會開始製作工具來讓生活更便利嗎?那就是猩猩!研究人員最近觀察到一些倭黑猩猩 (Bonobos, 又稱矮黑猩猩) 會將樹枝升級改造成箭、也會利用石頭或鋒利的角做成類似榔頭或匕首的工具使用,就像遠古時代的人類一樣!
![The bonobos used sticks to dig out food hidden under the ground and lever large rocks out of the way, as shown in the sequence of images above. Scientists say their use of tools resembles that of early stone-age technology used by our early human ancestors and may reveal how humans first began using tools](https://teepr.com/wp-content/uploads/2015/07/2A54A84700000578-0-The_bonobos_used_sticks_to_dig_out_food_hidden_under_the_ground_-m-12_1436348990676.jpg)
研究人員表示,多研究觀察倭黑猩猩的行為,將有助於人類學家們解開遠古時代的人類「怎麼開始使用工具」和「如何發展精進工具技術」的謎底。
![But.... sometimes it's just like, you just want to chill and start a fire with Grooook in private.](https://teepr.com/wp-content/uploads/2015/07/enhanced-buzz-12819-1363200690-6.jpg)
而這也意味著,靈長類使用工具的歷史可能遠比我們原先猜測的500萬年前更早!
![Is it too much to ask for one of those shower pouf things? They're like 99 cents.](https://teepr.com/wp-content/uploads/2015/07/enhanced-buzz-29528-1363203368-6.jpg)
學者分別對8隻來自動物園及7隻來自動物收容所的倭黑猩猩們做了一項實驗:他們營造了一些需要使用工具解決的情境,例如將食物埋在石頭底下,並留下了一些可能可以派上用場的棍子、鹿角及石頭供猩猩們使用。
![The researchers saw bonobos biting long branches to create spear-like tools that they used to jab at the scientists, who may have been perceived as a threat. The images above show how a female bonobo bit the end of the branches to sharpen the end and then brandished them outside of their enclosure](https://teepr.com/wp-content/uploads/2015/07/2A54A84100000578-0-The_researchers_saw_bonobos_biting_long_branches_to_create_spear-m-11_1436348964403.jpg)
最後共有2隻動物園的猩猩和4隻收容所的猩猩用了這些工具,而且是很有條理地使用工具來獲得食物。
其中一隻母猩猩利用牙齒磨利一根木棍,隨後她便用木棍戳身旁的觀察員。另一隻公猩猩甚至將石頭磨利來砍樹木,但學者也無法肯定這是不是因為他和人類相處的時間較長所致。
![This bonobo, called Kanzi, picked up the rock in front of him and used another rock to create sharp shards that he then used as tools. The new research suggests the behaviour may be more common than thought](https://teepr.com/wp-content/uploads/2015/07/2A54753700000578-0-image-a-14_1436349120207.jpg)
學者實驗後表示,雖然這實驗無法代表所有不管人工飼育或野生的倭黑猩猩都擁有相同的使用工具能力,但這的確證明了猩猩們是有這樣的潛力的!
![Bonobos like Kanzi have also learned how to build a fire and light it using matches, as shown above](https://teepr.com/wp-content/uploads/2015/07/1CB8D3DF00000578-0-Bonobos_like_Kanzi_have_also_learned_how_to_build_a_fire_and_lig-a-16_1436349343860.jpg)
