Quote ambiguously attributed. Hazen's contribution is largely irrelevant to my point - I simply noted that chiral molecules and chirality-influenced chemical interactions were common and readily available for "evolutionary process" to work with. That's easily sufficient - chiral molecules were abundant on the entire surface of the planet, and many of them (the clays, some crystals, lots of organics, anything with magnetic moment, etc) were capable of copying themselves, spreading via mechanical and other environmental forces, and so forth. It's important to remember that the modern extraordinary efficiency of living beings was completely unnecessary. If it took months and miles instead of minutes and micrometers to duplicate something, that was ok - nothing was stopping it.
