主题: 最可能的使地球上出现生命的机制是什么?
其一:
What is the most probable mechanism that caused life to emerge on Earth?
Difficult question! My guess would be that there was not a single mechanism responsible, nor did it happen from one day to the next.
这真是个复杂的问题!我猜测那不是单一的机制响应,也不是一天就能形成的。
Important mechanisms to name a few probably were:
可能的几个相关且重要的机制是:
1)The spontaneous creation of complex organic molecules from simple molecules in proto-earth.
1)复杂有机分子的自发创造性,从简单的分子到简单的生命。
2)The 3D complexity of very long organic biomolecules, that in combination with external energy can create complex chemical systems that are difficult to reach equilibrium.
2)有机生物分子经过很长一段时期形成三维复杂生命体 ,它包含了可以利用外界能量的复杂化学系统,艰难地维持着平衡。
Also these molecules can react with simpler compounds (CaCO3, aminoacids, etc) and create other molecules with ridiculously complex 3D spatial conformations like them and increase the available for life chemical reservoir.
这些分子可以响应更简单的物质(比如碳酸钙,氨等等),然后以无序而复杂的三维空间构型创造类似自身的其他分子,同时也创造了可供生命使用的化学能池。
3)The natural history of reactions favors (and in a way select) the most stable systems.
反应的自然历史有利于(并在某种程度上选择)最稳定的系统。
For example adhesive properties can make systems endure external events,
比如黏膜结构可以让系统池承受外界事件,
hydrophobicity can create membranes, pores, etc, which can protect and sequester reactions, deoxyribonucleic acids and their packaging can lead to relatively stable structures, etc.
疏水性可以创造隔膜,气孔等,用于保护和隔绝响应,DNA和它的组成物质可以拥有更稳定的结构。
