题目内容

科学家认为,手是使人能够具有高度智慧的三大重要器官之一,其余两个器官是可以感受到三维空间的眼睛和能够处理手眼传来的信息的大脑。在400万年的进化中,人类的手逐渐演变成了大自然所能创造出的最完美的工具。无论是远古还是现代,手都象征着人与神的活动,象征着权力、创造与智慧,对手的崇拜可以在不同的文明中见到。手相不只是江湖术士的花言巧语,科学也对此深感兴趣。研究表明,手指,特别是食指和无名指的长度,与人体的健康有关联。手指的生长和大脑的发育是在同一时期发生的,并且都与子宫内性激素的水平有关。如果孕妇怀孕期间睾丸素水平较高,生下的孩子就更容易成为左撇子,也更容易日后得心脏疾病或孤僻症。女性的无名指往往与食指一样长或者更短,男性的无名指则往往长于食指,而左撇子的无名指通常比食指长出许多。另外,无名指长于食指还是有音乐天分有表现。在哺乳动物中,人类的手独一无二。大拇指同其他四个手指相对的结构是人手的最大优越性,许多类人猿可以将自己的拇指和食指对合,但不能将拇指与中指、无名指以及小指对合,因为它们的手指不够柔韧。只有人类的手指十分灵敏,可以感觉到振幅只有0.00002毫米的振动。研究发现,大脑在说话时会变得活跃的那一部分,在做手势时同样也会活跃起来。科学家还发现,大脑控制手的活动的区域,分布在运动中枢里几个不同的部位,面积达到大脑皮层的四分之一。一个简单的手的动作,例如举起一怀牛奶送到嘴边,会使大脑皮层出现特别强烈的兴奋,这一直是令神经学家不解的迷。 下列说法,符合原文意思的是()

A. 在进化中手逐渐演变成了使人具有高度智慧的最重要器官
B. 通常左撇子的无名指比较长,故日后易得心脏疾病或孤僻症
C. 做手势有助于思考表达和记忆,手势是人类惟一的肢体语言
D. 大脑在说话时活跃的那部分和做手势时活跃的部分是一致的
