Windler, was preparing for the spacecraft to reach the critical point in its trajectory where the astronauts could insert their spacecraft into humankind’s first lunar orbit.
To drive home the critical point that the foundation of life is a congeries of ultrasophisticated molecular machinery gathered inside the nanobots called cells—and to give some background for showing what Darwinian evolution can and can’t do in the realm of the nanobots—in this appendix I’ll recount some highlights from the history of biology and take a look at how some work gets done in a real nanobot.
