This is what can be made utterly precise with the second recursion theorem, or some of its generalisation. You can look at my paper “Amoeba, Planaria and Dreaming Machine” where I explain self-reproduction, self-transformation, set-regeneration, and dreams, by using Kleene’s second recursion theorem, or John Case’s generalisation of it. A planaria, here, is a program that you can cut in many pieces, and each pieces can build the entire program back (self-regeneration). Nature used it, somehow, arguably.
