The 'pointer states' are the 'robust' states, which are able to survive and continue to announce themselves to their surroundings. The analogy with Darwinism is a bit strained, I'll agree. Zurek wouldn't be the first physicist to co-opt some aspect of evolution into physics. Lee Smolin comes to mind.

Presumably, upon decoherence, there must be an exchange of particles to announce the "pointer states" to an otherwise disorganized universe. From my long-ago military days, I suggest the term guide-ons. Everything that pops into reality sends out a growing ripple of guide-ons, and everything that exists lives in a "guide-on field." Gee, this is fun!
