Unformatted text preview: by Homo habilis. At seven sites he found that 57 percent of the flakes were rightoriented, and 43 percent left, a pattern almost identical to that produced today. About 90 percent of modern humans are righthanded: we are the only mammal with a preferential use of one hand. The part of the brain responsible for fine control and movement is located in the left cerebral hemisphere, and the findings above suggest that the human brain was already asymmetrical in its structure and function not long after 2 million years ago. Among Neanderthalers of 70,000 – 35,000 years ago, Marcellin Boule noted that the La ChapelleauxSaints individual had a left hemisphere slightly bigger than the right, and the same was found for 347

brains of specimens from Neanderthal, Gibraltar, and La Quina. Paragraph 1 在 We all know that many more people today are righthanded than lefthanded. Can one trace this same pattern far back in prehistory? Much of the evidence about righthand versus lefthand 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 righthanded, 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; righthandedness was therefore heavily predominant.
1. The phrase assisted in in the passage is closest in meaning to ○ initiated
○ helped with
2. It can be inferred from paragraph 1 that even when paint was sprayed by mouth to make a hand stencil ○ there was no way to tell which hand was stenciled
○ the stenciled hand was the weaker hand
○ the stenciled hand was the dominant hand
○ artists stenciled more images of the dominant hand than they did of the weak
Paragraph 2 在 Cave art furnishes other types of evidence of this phenomenon. Most engravings, for example, are lit from the left, as befits the work of righthanded artists, who generally prefer to have the light source on he best t left so that the shadow of their hand does not fall on the tip of the engraving tool or brush. In the few cases where an Ice Age figure is depicted holding something, it is mostly, though not always, in the right hand.
