【单选题】
阅读理解(在下列每小题中,选出一个正确答案) 简单地说,人类是在非洲演化出来的,大约是几百万年以前。但等到学会制作衣服和帐篷之后进入寒冷地区,大概只是几万年以前的事。而进入西伯利亚北极,大约是在两三万年以前,进入阿拉斯加北极,最早的证据是在一万两千年前。在如此短的时间里,伯格曼法则是发挥不了什么作用的。尽管如此,如果仔细观察一下,伯格曼法则在人类身上似乎还是留下了某些痕迹。例如,白人是在欧洲比较靠北的地方演化出来的,所以个子比较大。而黄种人是在亚洲温带地区演化出来的,所以个子比白人要小一些。同样的,在中国,北方人比南方人个子就要大一些,也许这也是伯格曼法则发挥作用的结果吧。 但是,以此类推到黑人,似乎就有点矛盾了。按理说,黑人一直生活在热带,个子应该最小。然而,现在的黑人不仅比黄种人个子大,有的甚至比白人还高大,美国的篮球运动员,大部分都是黑人。不过,如果到非洲去看看,还是可以找出伯格曼法则的蛛丝马迹来。在非洲中部的热带雨林地区,生活着一种黑人,叫做俾格,过着狩猎收集型的群体生活,它们与其他黑人的差别是:个子明显的矮小,平均只有1.3米左右,偶尔也有长到1.5米的,就算是“巨人”了。他们的皮肤颜色浅而发红,不像一般的黑人那么黑,面部长而体,额部、眼睛和牙齿都比较往前突出,更接近于人类的原始面貌,所以被称为“矮黑人”。按照伯格曼法则来推断,也许这种黑人才真正代表着原始的黑人,其他的黑人可能都是后来的变种。如果这样的话,那么伯格曼法则在人类身上的表现还是非常明显的。 (选自位梦华《伯格曼法则在北极》) (1)、[单选题] (1.5分) 下列各项中,不能说明画线句的一项是( )
