There's discussion of measuring DNA complexity; issues in extrapolation (there's evidence suggesting recent increases are hyperexponential, which would push back the origin of life even further); section 8 notes function complexity has increased much faster with the "mind" (as in what birds and mammals have) which is not reflected in DNA complexity (chimp-human encephalization rate is x100 faster).
I love the fresh perspective of not tying the origin of life to the origin of earth - nice and non-geocentric!
The rise of life doesn't have to be a universally unique event. It can easily rise in isolation on Earth, and in numerous other places that obey the laws of organic chemistry.
