The meaning of recapitulation in the GA-model of evolution

Unfortunately, we can’t be sure that the condition of optimality according to theorem 6c can be utilized by natural phenotypic evolution (possibly in GA as a model of a brain).

But there is a chance if recapitulation and the rules of genetic variation cooperate to a certain extent. For instance – provided that steps are stored and executed in consecutive order - crossing over may sum a number of steps from maternal DNA adding a number of steps from paternal DNA and so on. This is like adding vectors that more probably may follow a ridge in the phenotypic landscape. Thus, the efficiency of the process may be increased by many orders of magnitude.

If the steps are executed randomly, we may still get a certain adaptation, but it is not as good as it could be. See for instance Kjellström, 1996, in references

Moreover, the inversion operator has the opportunity to place steps in consecutive order or any other suitable order in favour of survival or efficiency. See for instance
