Evolutionary model as applied to world economics

  Evolution can be defined as a system in which the organism that is most adept to survive it's conditions will outlast those that are not as adept as it, or simply, the fittest survive.

 There's also a concept called Punctuated Equilibrium, which attempts to explain large expansions of speciation in the fossil record in certain periods of time. 

 The question I wish to give, is it possible that the latest crises is an example of the evolution of our financial system going through something similar to punctuated equilibrium? The world economic system in it's entirety can be likened to an evolutionary system, where hundreds of different forces affecting it's system force the components of the system ill-suited to it's surroundings die off, and the parts of the system best suited to the surroundings will survive.

 Tell me what you think.
