Skepsis on the scenario of Biological Evolution provided by stochastic   models
  Stochastic models, based on random processes, may lead to power law distributions, which provide long range correlations. The observation of power law behavior and the presence of long range correlations in biological systems has been demonstrated in various studies. The combination of the two just mentioned results, theoretical and experimental, supports strongly the scenario of biological evolution across different organisms. In the current Letter we explore in a general way, using the algebra of Nonextensive Statistics introduced by Tsallis and coworkers, if the processes which are described by a class of stochastic models are really random and discuss the results with regard to a possible biological evolution.
