I'm not the author (though some are accusing me of being his alt, lol), and I'll agree that Gough doesn't go as deep into the evolutionary mechanism as needed to really sell the idea to someone NOT already looking for an alternative explanation to the current model. Smolin does a better job of this in The Life of the Cosmos, to a degree, but if you guys didn't like how wordy Gough was here, you'd HATE how repetitive Smolin gets with the idea.
That said, I don't think the evolutionary explanation is hand-waved into play at all. I see your point about how it's a reverse approach to how biological natural selection was discovered, but I don't think that decreases its merit in any way, either. Smolin especially takes a deep look at the star formation process, how galaxies work, the structure we see in the cosmic web (and that was 1997!) and makes the comparison to biological organisms in so much as they're dynamic, homeostatic, out-of-equilibrium systems that seem fine tuned to carry out a process of increasing complexification. This, combined with the understanding (just jump on board for the story, you can get off after if you don't like it) that universes reproduce through black holes/big bangs and the similarities are, I think, compelling.
I'm not saying this is 100% definitely the truth and everyone should abandon CDM and string theory. I just think it's a compelling idea that deserves to be considered and discussed honestly, or perhaps even earnestly.
