The ‘weasel words’ example by Richard Dawkins, allegedly proving the possibility of evolution, is examined. It is considered in the framework of genetic algorithms, and a new model, which better reflects the process of natural selection, is proposed. Computer simulations of these two models are performed and compared with each other, and it is shown that in contrast to the original ‘weasel words’ example, which converges within a few hundred generations, the proposed new model does not converge even within a million generations. It is argued that the primary reason for the quick convergence of the former model is fine acknowledgements, which are not very realistic in the real world. In the latter model, the acknowledgments are ‘coarser’, which makes it much harder to converge. Moreover, an additional problem of multiextremity, which is not present in the former model due to its simplicity, clearly manifests itself in the new, less artificial, setting.
