我们看错了近400年

这是小蝌蚪的千军万马。和铁人三项的游泳比赛状态差不多。

我挺喜欢看的。看了好几遍。小蝌蚪游起来摇头摆尾的,左摆,右摆。

300多年前,荷兰微生物之父Leeuwenhoek发明了光学显微镜。这是个伟大的发明,虽然当时是单筒的,却让人们看到了以前看不到的微观世界。于是他就拿来看各种能想象得到的东西。男人还是调皮的,一个“偶然”,他想到自己身上某个部位。哈哈,这个东西怎么那么神奇,一结婚就会有孩子,奇怪吧。

这一看不得了,居然就看到了成千上万的小蝌蚪,摇头摆尾,奋勇前进。于是,这三百多年来,我们都是这么认为的。这个伟大的小东西,就和小蝌蚪一样,摇头摆尾,左摆右摆。。。。

直到最近,我们才知道,这是个错觉。

今天,科技的发展,我们的感官,已经可以借助电脑,三维,高能分辨率,高速摄影,。。。。

于是,有好事者再次观察了小蝌蚪。发现,并不是那么左摆右摆式的前进。

而是不对称地,单朝一个方向,螺旋式前进。和酒瓶的软木塞的螺丝起子一样。这也可以理解,只有这样,才能克服女性体内那么多的千山万水,最后成功扎进卵壁,创造新的生命。

这么多年,我们都是在二维空间观察小蝌蚪。培养皿是个平面。发表在论文上的照片也都是二维的。而如今,我们有了四维。3D,再加上高度的T。现在我们每秒可以拍出55,000幅照片。
