18S rRNA gene, encoded small subunit ribosomal RNA and 1800bp, was 80% in organism and regarded as highly conserved molecules in course of evolution, so 18S rRNA gene was the important marker for organism taxonomy and system evolution.
By incorporating variables that can comprehensively reflect system evolution into the financial asset structure and economic growth model of a country, we can see that such evolution is either promotional or obstructive to her financial asset structure and economic growth.

The proof is based on a detailed analysis of both the dynamical properties of the nonlinear system evolution and the asymptotic properties of the spectrum of random geometric graphs.
However, due to inherent randomness in the network caused by random packet arrivals or random packet marking, the actual system evolution is always of a stochastic nature.
Utilizing some empirical findings in relation to software system evolution, it is suggested that the ignoring of feedback may be a major reason why the software process is so difficult to improve.
