Question

we all know that many more people today

英语翻译
We all know that many more people today are right-handed than left-handed.Can one trace this same pattern far back in prehistory?Much of the evidence about right-hand versus left-hand dominance comes from stencils and prints found in rock shelters in Australia and elsewhere,and in many Ice Age caves in France,Spain,and Tasmania.When a left hand has been stenciled,this implies that the artist was right-handed,and vice versa.Even though the paint was often sprayed on by mouth,one can assume that the dominant hand assisted in the operation.One also has to make the assumption that hands were stenciled palm downward—a left hand stenciled palm upward might of course look as if it were a right hand.Of 158 stencils in the French cave of Gargas,136 have been identified as left,and only 22 as right; right-handedness was therefore heavily predominant.

Answer 1

我们都知道现在惯用右手的人们比惯用左手的多得多.如果追溯这种现象到史前呢?很多证据显示右手对抗与左手的优势来源于发现在澳大利亚和其他地方以及冰河时期的法国,西班牙和塔斯马尼亚岛的岩石遮蔽物的模板印刷.当惯用左手的人用模板印刷时就暗示了这个艺人是惯用右手的,反之亦然.即使涂料经常被喷洒在嘴部,人们仍可以认为占优势的手在操作中起辅助作用.
人们也可做出双手掌心朝下印制模板的假设——一只掌心向上的左手打仍然看起来像是一只右手.在法国Gargas洞穴的158块模板中有136被认定为左手,而被认定为右手的仅有22块；因此惯用右手者完全占据优势.
