Entertainment 我们为什么生病
Posted on 2010-04-28

自然选择的中心思想虽然简单,但是常常被人误解。无论什么时 候生物体的遗传性变异导致了不同的生存率和生殖率时,子代数目更 多的个体所带有的基因在每一代所呈现的次数会变得更为频繁。于是, 许多代之后,生物体以各种方式逐渐变化,以便更好地适应它们所处 的环境。对生物体而言,这不仅仅是一种似是而非的观点,而且是有 充分证据的必然结果。假定生物体具有可遗传性变异的潜能,那么通 过自然选择的进化就肯定会发生。超出我们用生物形态和功能所能作 出的有力解释之外,还存在一个更为奇妙的复杂世界。达尔文医学的 贡献之一是,表明了自然选择怎么能够成为极其有效的适应性基础, 而同时使我们容易遭受病痛。人的这种脆弱性不是来自机体的任何规 划或代谢失衡,而是来自自然选择过程的基本的限制。我们不能改变 这一切,但是我们能够理解它,由此找到种种方法来保护我们自己, 使人类生活更加美好。
