生物多样性 2

in #wherein4 years ago

据说,地球上共有接近一千万种生物,而目前科学家已经了解的物种,大概有120万左右。数量如此庞大,一个人终其一身也看不完人类已了解的物种,这生物多样性真的令人咋舌。

不过,这么多的生物,里面的每一种,不管数量再多,其表现都是差不多的——比如家蝇喜欢逐臭,蟑螂无所不吃…

人类,也是这千千万万物种中的一个,但就差异性来说,人的分类,远多于这近一千万的生物种类,生物多样性碰到人的多样性,那时小舢板碰到大航母,没法比。

王小波说过:

人与人的差别,有时大于人与猪的差别。

这是真的。不管你多么惊诧,多么想不通,总会有人向你演示这种差别。

软哥 @softmetal说:

如果地球上只剩人类,其余所有生物都灭绝了,那人类也会很快就嗝屁了。

我倒觉得未必如此。

如果地球上只有人类,应该很快会发展成为一个丰富的群体:有老鼠人,蟑螂人,蚂蚁人,蜜蜂人,也会有鹰人,虎人…总之金字塔层级发展会登峰造极,世界的精彩程度,阴险程度,心碎指数都会呈指数级增加。

总之,自古难测是人心,人类的差异,远多于生物种类之间的差异。像我儿子,目前认为世界上只有好人和坏人,路漫漫其修远兮……
