Strikingly, he demonstrates that Darwinian evolution is the biological expression of a deeper, well-defined chemical concept: the whole story from replicating molecules to complex life is one continuous process governed by an underlying physical principle. The gulf between biology and the physical ...

What is Life?: How Chemistry Becomes Biology 这篇书评可能有关键情节透露 一日不读书,尘生其中;两日不读书,言语乏味;三日不读书,面目可憎。——黄庭坚 真的好久好久没认真读书,更没写一些读书感想,这本书虽然好读,也断断续续读了一个月,所以如果这次写的太过书面或是很多错误,欢迎各位指正。 写这篇读书笔记...
在本书中,生命被定义为是通过复制反应得到的一个能够自我保持动力学稳定的动态反应网络。生命就是靠指数增长的力量作用于化学复制系统而产生的化学结果而已。生命即复制的化学。 而死亡是一个系统从动态的复制世界逆向回到常规化学世界,长生不老不存在是因为短暂和动态性是生命的基础。 达尔文的进化论告诉我们,一个低...
