A wonderfully lucid and illustrated walkthrough of how life’s molexular machineries work. From the sheer difference of architectural principles at nano-scale (gravity drops the ball, diffusion rules!), to the four basic structures of life and how they build everything to what, if anything, can be learned from all this - rarely have science been so readable and reflective. This was written pre-CRISPR, but even the “recombinant DNA” section was principally robust. Evolution does not design, it merely tinkers on working prototypes and kills the non-functioning ones - evolution always builds on legacy code! Evolution’s “burn down chart” be like 97% operating and 3% tinkering (with very high error rates).
