Determinism: Determinism in comparison to stochastic behavior depends on the number of dimensions in the system. The number of dimensions in a system is the total number of independent units (after converting the derived units) present in the system. For example, the number of dimensions in velocity , is 1+1=2. A dimension of ten or more is not computationally feasible and stochastic behavior is used in such conditions. The difference between Stochastic behavior and Chaotic behavior is that the output of Chaotic systems is exponential whereas that of Stochastic systems is random
Sorry. That's a lot of bull... All you keep doing is providing circular links to chaos theory, which is quite interesting.
But you are still not making your point. How is stochastic processes related to evolution?
And by the way, what is your point?
