As I show in the 2008 publication Computational Ontogeny, self-replicators are partitioned into organs that can be separated (or, teased from one-another), in such a way that the constructor itself is clearly divided from all other organs. Further, the constructor itself can be partitioned into proto-constructors, and some of these proto-constructors can be added to the configuration of the self-replicator, after the self-replicator begins its behavior, and by the daughter self-replicator. The mother constructs a machine zygote. Mine is the first constructed example. See the Partial Constructor, as available in the open source tool known as Golly.

I very much recommend that you obtain and use Golly. It is the premier cellular automata simulation software.
