One faces at least three basic problems of genuine biological autonomy： （1） if biological autonomy is not physical, where does it come from？ （2） Is there a room for biological causes？ And （3） how to obtain a workable model of biological teleology？ It is shown here that the solution of all these three problems is related to the quantum vacuum. We present a short review of how this basic aspect of the fundamentals of quantum theory, although it had not been addressed for nearly 100 years, actually it was suggested by Bohr, Heisenberg, and others. Realizing that the quantum mechanical measurement problem associated with the ＂collapse＂ of the wave function is related, in the Copenhagen Interpretation of quantum mechanics, to a process between self-consciousness and the external physical environment, we are extending the issue for an explanation of the different processes occurring between living organisms and their internal environment.
