Some days, the new readily available research provides only accredited help, very first structure or prima-facie plausibility. As usual, upcoming works may find the concept looking for and you may specific hypotheses completely wrong. In closing, i (i) compare this new conditions beneficial to the spread of monogamous versus polygynous relationships, (ii) envision alternative hypotheses toward pass on out of monogamous marriage, and you can (iii) speculate about how wedding assistance will be connected to the rise from democratic institutions and commercial financial increases.
