This is purely my imagination.
我认为，生命的出现，不会是分子的偶然聚集。就象人体，受两个因素控制，按预定的计划发展：脑细包，肝细包，muscle, etc., they all develop at the proper time, under the right condition.
These two controlling factors are: 1) DNA; 2) Outside environment.
If we regard the Universe as a living body, it is also controlled by the same two factors. The development of the Universe is according to the Universe's DNA, affected by its outside environment.
In this view, individual life form works together seamlessly to create bigger life form; just like the countless cells in the human body working together to create the human body. No one individual is selfish, they all work towards the bigger goal. How does the "whole" coordinates the "individual"? This is where the second factor comes in. The DNA of the individual life form is controlled by the "outside environment": certain DNA segment of the individual is turned on/off with the changing environment. Each individual can affect the environment; so this is a very efficient way for individuals to communicate to each other, to work together for the bigger "whole".
