The phenomenon of "information drift" (genetic drift) is not unique to living organisms. If we try to reconstruct any complex system without changes in probability distributions, random changes will occur every time. The descendant system is never the same as the ancestral one.

{(A game): A computer population consists of 1000 diploidal organisms. There are two alleles in this population (B dominating and Y recessive) decoding color. Hence, the organisms can be blue (the ones with genotype BB, BY, YB) or yellow (genotype YY). Chose the frequency of the alleles. The computer will use the frequency to randomly assign a genotype to each organism.}
