It's interesting that Lee Smolin used the idea of an evolutionary Landscape of physical law back in 1995
http://arxiv.org/gr-qc/9505022
We just had that young quantum gravity researcher Leonardo Modesto at Marseille remove the Black Hole singularity so that spacetime extends thru the black hole to somewhere else ("Disappearance of the Black Hole Singularity in Quantum Gravity" http://arxiv.org/gr-qc/0407097 )
Smolin explicitly anticipated that kind of result in Quantum Gravity---eliminating classical GR's Black Hole glitch----in his 1994 paper
"The fate of black hole singularities and the parameters of the standard models of particle physics and cosmology"
http://arxiv.org/gr-qc/9404011
This 1994 already is describes the Landscape concept but doesn't apply the word "landscape" to it.
----from 1994 abstract---
The implications of a cosmological scenario which explains the values of the parameters of the standard models of elementary particle physics and cosmology are discussed. In this scenario these parameters are set by a process analogous to natural selection which follows naturally from the assumption that the singularities in black holes are removed by quantum effects leading to the creation of new expanding regions of the universe.

In the 1995 paper the analogy is drawn between the genes of an organism and the parameters of physical law which generate the universe---the genes are to the organism as the fundamental constants and the laws of physics are to the universe----different values of the constants means a different universe.
In evolutionary Biology the ensemble of all possible sets of genes for an organism constitute a "Fitness Landscape" and this will have hills and valleys determined by a fitness function, with selection driving the gene pool to higher nearby levels of fitness (reproductive success).
Smolin draws the analogy explicitly (see e.g. page 33) and proposes a way the ensemble of possible sets of physical constants can be seen as a reproductive fitness Landscape.
the act of reproduction in this case being the formation of a black hole.
He is able to make a falsifiable prediction from this--which as of today still stands and has not been refuted
"... leads to a definite and testable prediction, which is that, Almost every small change in the parameters of the standard models of particle physics and cosmology will either result in a universe that has less black holes than our present universe, or leaves that number unchanged..."
Have to go, will get back to this later
