A Natural History of Complexity: Complexity accreted like coral, with no architect behind it

I keep meeting the same thing at human scale. On a plant I once assumed the piping and controls had been laid out as one design, until I traced it line by line and found it had simply accreted, years of separate fixes with no plan behind any of them. The pride my colleagues took in "their" system dropped a little once they accepted that no one had authored it. The tangle was a residue, not an achievement.

That is the argument. Most complexity was not built, it accumulated. Coral reefs grow a centimeter or two a year, polyp on dead polyp, and the Great Barrier Reef is some twenty thousand years of that with no architect. Maynard Smith and Szathmary catalogued the major transitions that stacked biological complexity up over deep time. Constructive neutral evolution shows cellular machinery piling up by drift that selection never asked for. QWERTY, Gould and Lewontin's spandrels, path dependence: the same story, complexity that stuck because going back had become too costly. Darwin closed the Origin in 1859 with an entangled bank whose elaborate, interdependent forms were "produced by laws acting around us", not by a maker.

This is a short book about the natural history of complexity, self-organization and spontaneous order, symbiogenesis and the major evolutionary transitions, constructive neutral evolution, spandrels and path dependence, and why so much of our own tangle was accreted rather than achieved.

This book is written from an Indonesian operator's context, but a system that grew by accretion instead of design is a thing you can find in any workshop, cell, or state.
