※ 引述《DarkD (達克豬)》之銘言: : 最後的整合題 : 6) Nick Toth, a modem right-handed toolmaker. has shown that prehistoric tools : were knapped to fit the right hand : PA. 6: Occationally one can determine whether stone tools were used in the : right hand or the ledt, and it is even possible to assess how far back this : feature can be traced. In stone toolmakingexperiments, Nick Toth, a : right-hander, held te core (the stone that would become the tool) ib his ledt : hand and the hammer stone i nhis right hand. As the tool was made, the core was : rotated clockwise, and flakes, removed in sequence, had a little crescent of : cortex(the core's outer surface) on the side. Toth's knapping produced 56 : percent flakes with the cortex on the right, and 44 percent left-oriented : flakes. A left-handed toolmaker would produce the opposite pattern Toth has : applied these criteria to the similarly made pebble tools from a number of : early sites (before 1.5 million years) at Koobi For a, Kenya, probably made by : Home habilis. At seven sites he found that 57 percent of the flakes were : right-oriented, and 43 percent left, a pattern almost identical to that : produced today. : 好像沒錯阿....@@? : 麻煩板友幫忙指出來,看很久都看不出所以然 我是這麼解的 你參考看看: 選項Nick Toth has shown that prehistoric tools were knapped to fit the right hand(Nick指出史前工具乃是製作來供給右撇子使用) 仔細看第六段的意思應該是tools were made 'BY' right-handed toolmaker (工具是由右撇子的人做出來的, 根據NICK的實驗結果和實際發現吻合推知) 這樣看的話這個選項的意思有點改變了原意 所以不選它 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 123.193.34.160
