    死亡的意义

    "我们应该考虑死亡的意义--不为了逃避它,不为它辩护,也不为了寻求永生,而是为了努力证明它为人类存在赋予了意义"

    这是法国哲学家艾玛纽尔.列维纳斯对死亡的深刻阐述.

    最近看到一篇文章说物种之所以会死亡,是因为在进化过程中产生了衰老基因,也正是这种基因增强了物种繁衍的能力.

    怎么说? 就是我们在为自己自身延续付出了生命的代价!

    科学家是这么解释的:

    从一开始我们老死都是由衰老基因决定的,这些老化现象出现在所有原生物上,也就是所有参与进化的生物都有衰老基因,细菌则很少有老化现象!

    所以衰老是进化的阴谋,说穿了我们为了进化必须衰老!

    科学家通过实验发现被改变pit1基因的老鼠寿命达到了4年,相当于这种动物个体正常寿命的2倍!

    不过有失必有得,之后生命体丧失繁殖力后,自然选择就无情地将它们抛弃,任由有害健康的突变在它们的基因组中积累.

    结论出来了:人类要想更长寿,就要牺牲自己的生育能力!

    那么谁会为了长寿去牺牲自己的生育能力呢?

    在这里我想到一个问题,那么我们是从一开始就伟大的选择放弃自我,去实现进化和繁殖?

    还是因为我们的贪婪,上帝将死亡赋予我们呢?
