动物世界中的左撇子

①在美国的倒数前7任总统中，有4位都是左撇子——福特、老布什、克林顿和奥巴马。左撇子并非生理缺陷，而是正常的遗传现象，科学家称它为“偏侧优势”。

②动物世界中也有偏侧优势的现象吗？有，没准你家的猫咪就是常喜欢用左前爪的左撇子呢。来自英国的研究人员以42只家猫为研究对象，让它们完成一项复杂的取食任务——从一个窄口罐子中取出金枪鱼肉。结果发现，在十几次的取食测试中，21只母猫有20只都使用右爪。而21只公猫中有20只习惯用左爪……研究人员说，家猫对左右爪的使用偏好只有在完成一些较复杂的任务时才十分明显。这就好比对人来说，打开一扇门用左右手都可以轻松搞定，但涉及用筷子或写字这样的复杂行为时，就开始体现出左手或右手使用偏好。

④按照上面的实验结论，猫咪们是“男左女右”的坚定执行者，宠物狗们则没有这么统一。澳大利亚悉尼大学兽医学院的保罗·麦克里维（Paul McGreevy）博士领导的研究小组在对270只种类不同的狗进行长期观测后发现，15%的狗是右撇子，15%的狗则是“左撇子”，剩下70%的狗没有明显的使用偏好。麦克里维认为，左撇子或右撇子的狗更容易被训练成为适合特定工作的狗，比如导盲犬或警犬。那些对左爪或右爪缺乏使用偏好的狗更容易对声音产生恐惧。他说：“如果一只狗被打雷声或鞭炮声吓得半死，显然它不适合做缉毒犬或导盲犬。”推广麦克里维博士的方法，可以帮助人们在训练特种狗和挑选优秀的宠物狗时，节约大量的时间和金钱。

⑤如何判断你家的宠物狗是“左撇子”还是“右撇子”？并不是一件容易的事情。麦克里维和他的研究小组准备了一种圆筒状的容器，里面盛好狗食。接受测验的狗要吃容器里的食物，就必须用一只爪子按住容器，使之静止不动。每只狗接受100次这样的测验，然后研究人员根据这100次内这只狗使用左爪和右爪的偏好，判断这只狗是“左撇子”还是“右撇子”。有时候，仅判断一只狗的偏侧性就需要花费4小时左右时间。如果你的时间充裕，不妨在家中试试看？ 家里养的宠物鹦鹉的同学们！如何来检测你家的鹦鹉是哪侧优势呢？可以准备一些水果给它，看它最经常用哪只爪子来抓。科学家们的研究指出，大部分鹦鹉都是左撇子。想一想，在田径场上跑步时，你喜欢逆时针还是顺时针跑？大部分人及正规的竞赛都选择逆时针方向奔跑，这是因为我们人类的心脏在身体的左侧，相对右侧更沉，逆时针绕圈更稳定。因此，右腿比左腿迈的步子更大的“左腿主导马”（左撇子马），因左拐时更具优势而更受到骑手们的青睐。有些驯马者还会采用遮住马的左眼，鼓励马儿更大幅度地去迈右腿的方式来调整那些“右腿主导马”（右撇子马），以便它们能更好地竞赛。软体动物蜗牛，好像没有明显的肢体来表决自己对于左还是右更青睐，但通过它们硬壳上的清晰螺纹，科学家发现，在已知的70000种蜗牛中只有大约10％是左旋的（左撇子），右旋的（右撇子）占了绝大多数。

⑥2009年一篇来自著名科学杂志Nature的文章指出，决定蜗牛的壳左右旋转的是一个名叫Nodal的基因。该基因在蜗牛受精卵分裂成4个细胞时开始起作用，如果将这个基因掩盖住，不让它作用，蜗牛的壳的螺旋现象就消失了。

Lisa was running late. Lisa, 25, had a lot to do at work, plus visitors on the way : her parents were coming in for Thanksgiving from her hometown. But as she hurried down the subway stairs, she started to feel uncomfortably warn. By the time she got to the platform, Lisa felt weak and tired—maybe it hadn’t been a good idea to give blood the night before, she thought. She rested herself against a post close to the tracks. Several yards away, Frank, 43, and his girlfriend, Jennifer, found a spot close to where the front of the train would stop. They were deep in discussion about a house they were thinking of buying. But when he heard the scream, followed by someone yelling, "Oh, my God, she fell in!" Frank didn’t hesitate. He jumped down to the tracks and ran some 40 feet toward the body lying on the rails. "No! Not you!" his girlfriend screamed after him. She was right to be alarmed. By the time Frank reached Lisa, he could feel the tracks shaking and see the light coming. The train was about 20 seconds from the station.

It was hard to lift her. She was just out. But he managed to raise her the four feet to the platform so that bystanders could hold her by the grins and drag her away from the edge. That was where Lisa briefly regained consciousness, felt herself being pulled along the ground, and saw someone else holding her purse. Lisa thought she’d been robbed. A woman held her hand and a man gave his shirt to help stop the blood pouring from her head. She tried to talk but she couldn’t, and that was when she realized how much pain she was in. Police and fire officials soon arrived, and Frank told the story to an officer. Jennifer said her boyfriend was calm on their 40 minute train ride downtown—just as he had been seconds after the rescue, which made her think about her reaction at the time. "I saw the train coming and I was thinking he was going to die", she explained.
