In other cases, the fresh new offered facts provides merely accredited help, first feel or prima-facie plausibility. As usual, upcoming functions may find the theory wanting and you can certain hypotheses incorrect. To summarize, we (i) examine brand new requirements favorable into the spread of monogamous as opposed to polygynous matrimony, (ii) think choice hypotheses to the give regarding monogamous matrimony, and (iii) speculate about how wedding expertise could well be linked to the increase regarding popular institutions and you can industrial financial development.
