New replicator found?

In an understandably vague article, that tries to explain in layman’s terms the meaning of a new theorem about the interactions of quantum states with the environment, Nature announces the results of a team of US physicists, that aims to explain the objective shared reality we observe, through the involvement of a new replicator. This new replicator, multiplying, with variation, exposed to the selective pressure of a limited environment or resource, is what they call the imprint of the pointer state.

After biological genes, memes from Dawkins, and universes (as in Smolin‘s interpretation of the meaning of the black-hole singularity), we seem to have the idea of a new replicator to play with.
