I’d say it gets more constructed and less evolved the further up the hierarchy of civilisation we get. A merchant of 1320 had relatively few laws to contend with, a corner shop in 2020 could not function without many layers of engineered rules for the people who provide them with the services they are themselves required to use due to other engineered rules for the benefit of their customers.
This makes me wonder what laws and tedium of administration merchants of the 1320's would complain about. I'm sure they still had a few depending on the region, and maybe more severe possible outcomes (highway robbery, unlawful arrest because of the influence of a rival merchant, arbitrary taxation and tariffs, etc.).
Yup. I think also languages were much more variable, and doing accounting in Roman numerals was so hard they did it twice and averaged the answers, and contracts and tax receipts were done by carving marks in sticks (hence, apparently, the etymology of "stocks").
Construction and evolution aren't mutually exclusive, instead they are different parts of the process, the generation and the scoring functions really. Evolution works not because of DNA (although it is one mechanism) but survival bias in a literal sense. Things which survive longer and increase in number we wind up with more of.
